SYSTEM SPECIFICATION FOR THE EDIM MODEM

1 SCOPE 1.1 Identification This specification establishes the system requirements for a Frequency Division Multiple Access (FDMA) Enterprise Digital Intermediate Frequency (Digital IF) Multi-Carrier (EDIM) Modem System to be used with Department of Defense (DoD) and commercial satellite systems. The EDIM Modem System includes the EDIM Modem, associated Graphical User Interface (GUI) and all supporting software. 1.2 General The EDIM Modem addresses L-Band port congestion at DoD SATCOM gateways by offering a multi-carrier modem capability. The EDIM Modem also serves selectively as a flexible general-purpose Digital IF infrastructure appliance. As a flexible Digital IF building block, the EDIM Modem enables and accelerates the migration of DoD SATCOM gateway architectures from L-Band media to Digital IF media. 1.3 Multi-Carrier Modem Operation The EDIM Modem is a fully integrated multiple carrier modem addressing growing DoD Enterprise SATCOM needs for high-density high-performance Internet Protocol (IP)-centric FDMA modem operations. The EDIM Modem supports multiple point-to-point SATCOM links by carrying Ethernet data traffic over multiple carriers employing both L-Band and Digital IF interfaces. The ability to support multiple carriers over L-Band immediately addresses L-Band switch congestion issues at Enterprise SATCOM gateways. The EDIM Modem is a user-friendly upgradeable platform intended to introduce various new modem capabilities, both immediately and through subsequent upgrades. 1.3.1 Modem Emulations The EDIM Modem supports an efficient subset of NATO STANAG 4486 Ed4 (Enhanced Bandwidth Efficient Modem, a.k.a. EBEM) waveforms with the possibility of pursuing future upgrades to support DVB-S2X hub waveforms in accordance with (IAW) ETSI EN 302 307-2. Provisions for ensuring high performance efficient operation include integrated waveform equalization and integrated interference cancellation. Additional improvements in performance efficiency are realized through interoperability with satellite network power control systems, both generally and in the interest of dynamic resource allocation (DRA) of satellite power with respect to (WRT) data traffic demand and link quality. 1.3.2 Data Traffic Cover The EDIM Modem is intended for operation with encrypted (black) data traffic. The EDIM Modem provides encryption for all its carriers for purposes of obscuring headers to prevent adversary data traffic analysis. The initial data traffic cover

1 EDIM Modem Solicitation # W52P1J-21-R-0001 Section 4: System Specification 30 Sept 2020 capability is compatible with that of NATO STANAG 4486 Ed4 (EBEM). The EDIM Modem is to be certified at Level 1 IAW National Security Administration (NSA) and/or Security Level 2 IAW Federal Information Processing Standards (FIPS) Publication (PUB) 140-2 or FIPS PUB 140-3, subject to guidance from NSA and from the National Institute of Standards and Technology (NIST). The EDIM Modem supports the National Security Administration (NSA) Public Key Infrastructure (PKI) key format for legacy interoperability while also supporting NSA Key Management Infrastructure (KMI) and Over The Network Keying (OTNK) formats for future operations. 1.4 Digital IF Migration Digital IF Enterprise terminal infrastructure is key to supporting DoD SATCOM growth and resilience. The EDIM Modem facilitates the transition of DoD Enterprise Earth Terminals from the present L-Band architecture to the pending Digital IF architecture. 1.4.1 Dual IF Interface Sets The EDIM Modem supports the transition from L-Band to Digital IF infrastructures by offering dual IF interface sets. Operation over the L-Band IF is compliant with MIL-STD-188-165B. The Digital IF interface is ANSI/TIA-5041 compliant with provisions for carrying carrier frequency and power information as well as the flexibility to implement valuable and user-friendly protocol enhancements. Digital IF performance supports end-to-end performance of Digital IF signal chains equivalent to or exceeding the performance required of corresponding L-Band signal chains. 1.4.2 Digital IF Functions The EDIM Modem further supports the SATCOM architecture L-Band to Digital IF transition by delivering Digital IF functions necessary to the Digital IF Gateway architecture. In addition to functioning as a Digital IF modem bank, the EDIM Modem may be otherwise repurposed, by configuration, to function selectively as a Digital Conversion System (DCS), or as a Wideband Signal Processor (WSP), or as a multi-carrier L-Band Modem Adapter (LMA). The EDIM Modem is also capable of several key Digital IF test features for measurement of Digital IF performance in the Digital IF domain. This strategic combination of features enables the EDIM Modem to support the rapid transition of Enterprise Earth Terminals from L-Band to Digital IF. The EDIM Modem is therefore the lynchpin Digital IF architecture migration appliance. 1.5 Applications and Usage The initial application of the EDIM Modem is for Enterprise Earth terminal deployment. The Government may consider revised or upgraded versions of the EDIM in the future for application in shipboard, land mobile, airborne SATCOM, special missions and virtualization. Such revisions may include upgraded capabilities and/or new size, weight and power (SWaP) requirements.

3.2.4.1 Digital IF Capacity The Digital IF interface, as a minimum, shall simultaneously support up to: • At least 8 carriers or channels total each on uplink and downlink • At least one aggregate channel each on uplink and downlink • At least 16 bit sample sizes • At least the full L-Band BW IAW 3.2.3 3.2.4.2 IP Addressability Within the EDIM Modem, the sources and sinks of Digital IF carrier and aggregate streams shall be associated with configurable port numbers of a configurable IP address. 3.2.4.3 Digital IF Protocols The Digital IF interface shall support Digital IF streaming compliant with ANSI/TIA- 5041 FAST OSDI protocols subject to revision by the Contractor and Government approval as indicated in this section. Contractor revision of ANSI/TIA-5041 FAST OSDI is intended to: • make Digital IF operations as simple as possible for the EDIM Modem user specifically • make Digital IF operations as simple as possible for Digital IF users in general • support growth, both qualitative (capabilities) and quantitative (rates and levels), far beyond the life cycle of the EDIM Modem Digital IF protocol features and capabilities contemplated for making Digital IF operations simple for the user and for supporting growth far beyond the life cycle of the EDIM Modem include the following: a. Clear mandatory Digital IF stream provisions for conveying or otherwise determining carrier power and frequency information as follows: i. on uplink, carrier or channel frequency and power to be delivered upon analog conversion, so that the user can configure carrier power and frequency at the DM or LMA consistent with present DoD SATCOM Gateway L-Band operations ii. on downlink, carrier or channel power and frequency delivered at the Digital IF conversion point, so that received carrier power and frequency can be determined and displayed at the DM or LMA, consistent with present DoD SATCOM Gateway L-Band operations iii. carrier or channel frequency in Hz, without artificial range constraint, to the limit of present FAST OSDI protocol constructs, which appears to be ±8.8 THz in increments of 0.954 mHz. The purpose is to support unpredictable growth beyond the EDIM Modem life cycle. This is a protocol requirement, not an EDIM Modem requirement to support carrier frequencies beyond what is explicitly specified for the EDIM Modem (e.g. 400 GHz let alone 8 THz). 22 EDIM Modem Solicitation # W52P1J-21-R-0001 Section 4: System Specification 30 Sept 2020

iv. ability to convey a “zero signal” condition. The purpose is to convey zero signal presence to the exclusion of digital sampling noise, which could be significant when employing small sample sizes. v. power levels in dBm, without artificial range constraint, over the full range possible with existing FAST OSDI protocol constructs, which appears to be ±256 dBm in increments of 0.0078125 dBm. The purpose is to support unpredictable growth far beyond the EDIM Modem life cycle. This is a protocol requirement, not an EDIM Modem analog IF requirement to support levels (e.g. -150 or +150 dBm) beyond what is otherwise specified. vi. for use in L-Band conversion WRT L-Band conversion systems. The purpose is to enable accurate level translation in DCS and LMA processes. vii. for use in direct RF conversion WRT direct RF conversion systems. This is a protocol requirement with the purpose of addressing growth beyond the EDIM Modem. This is not an EDIM Modem requirement for direct RF conversion. viii. The contractor is encouraged to consider potential support of burst transmissions and fast frequency hopping applications when recommending any alternate ways of conveying time, frequency and power information. This is a protocol requirement with the purpose of addressing capability growth beyond the EDIM Modem. This is not an EDIM Modem requirement for burst transmission or frequency hopped waveforms. b. Ability to address Digital IF streams between IP addresses and ports (VVV.WWW.XXX.YYY:ZZZZ) to the exclusion of any necessary i. stream number assignment ii. packet, stream or object class identification or restriction iii. WSP configuration necessarily first before DCS or DM iv. obstacle, restriction or additional configuration steps due to object or class construct requirements v. The intent is for the user to benefit from full unrestricted unhampered Digital IF connection flexibility as offered by today’s DoD SATCOM Gateway L-Band architecture c. Support for Digital IF network connectivity between stream sources (stream origination points) and sinks (stream destinations) to include i. Auto-discovery to enable auto-population of configuration screens with Digital IF elements available on the Digital IF network ii. Cooperative source-sink establishment of Digital IF streams where 1. establishment will be initiated at either the source or the sink 2. streaming is predicated on user consent at both ends iii. Support for relevant configuration exception signaling and user warnings, e.g. parameters out of range, e.g. an EDIM Modem capable of 950 to 2000 MHz requested to operate as a DCS from 600 to 800 MHz, or requested to support power levels beyond equipment operating ranges

23 EDIM Modem Solicitation # W52P1J-21-R-0001 Section 4: System Specification 30 Sept 2020

Support for flexible sampling to include i. complex sample rates, without artificial range constraint, to the limit of present FAST OSDI protocol constructs, which appears to be ±8.8 THz in increments of 0.954 mHz. The purpose is first to support EDIM Modem BWs to 1050 MHz, then later to support unpredictable growth far beyond the EDIM Modem life cycle. This is a protocol requirement, not an EDIM Modem requirement to support complex sample rates beyond those needed to support 1050 MHz of BW. ii. sample rate granularity to below the greater of 1 kHz or 0.1% rather than the present integer power of 2 restriction. The purpose being to enable control of the Digital IF stream rate for the sake of transport efficient Digital IF streams rather than implementation efficient Digital IF streams at necessarily higher stream rates. iii. sample size adjustable from 4 to 16 bits per sample, rather than fixed at 16. The purpose being to enable control of the Digital IF stream rate for the sake of transport efficient Digital IF streams rather than implementation efficiency necessitating higher stream rates. e. Lowest practical reduction of Digital IF stream rate for the sake of terrestrial transport efficiency f. Allowable variation in packet sizes for various reasons, including i. allowable variation in sample count when sample sizes are below 16 bits so that bytes don’t have to be “stuffed” ii. increased speed of Digital IF stream transmission through network switches and routers g. Optional use of Fourier coefficients rather than time samples to relieve WSP computational load at the expense of DCS computational load h. Any additional capabilities required to meet the requirements specified in this document To the extent that these capabilities are: • not native FAST OSDI capabilities • not sufficiently documented within ANSI/TIA-5041 to support full interoperability with minimum manual configuration • otherwise ambiguous in any respect within ANSI/TIA-5041 the contractor shall propose and fully disclose complete comprehensive non- proprietary draft revisions to ANSI/TIA-5041 (ANSI/TIA-5041 FAST OSDI Draft Revisions) to introduce, or to otherwise edit, where necessary, the specification of

Each delivered unit shall be accompanied by a complete copy of its respective PQT report. Electronic copies shall be made available to the Government upon request. PQT shall include those verification activities indicated in APPENDIX C. PQT shall not proceed until the contractor-developed PQT Plan and PQT Procedures have been approved by the Government. PQT shall not be deemed accepted until all test cases are successfully completed by the contractor. 4.1.3.2.2 Early Life Defect Prevention PQT shall include provisions to prevent or otherwise minimize early life defects. The effectiveness of these provisions shall be continuously monitored by the contractor WRT the number of defects found during the first six months of item use (early life). Based on the results of early life defect monitoring, provisions to detect and prevent early life defects may be altered subject to Government approval. Early life failures shall require that provisions to prevent early life defects be strengthened. 4.2 Expanded Verification Cross Reference Matrix (EVCRM) EDIM Modem requirements specified in Section 3 shall be verified IAW the VCRM in APPENDIX C (TABLE XI), which identifies FAT and PQT requirements for inspection, analysis, demonstration, or testing corresponding to EDIM Modem requirements. The contractor shall further prepare an EVCRM, as part of the FAT

121 EDIM Modem Solicitation # W52P1J-21-R-0001 Section 4: System Specification 30 Sept 2020

Plan, based on the APPENDIX C VCRM. The EVCRM shall ensure complete FAT and PQT verification of the following: • All EDIM Modem requirements specified in Section 3 • All EDIM Modem requirements which flow down from Section 3 requirements through external references • All EDIM Modem requirements which flow down from documents referenced at all levels from other referenced documents • All additional features and capabilities introduced by the contractor The EVCRM shall be subject to Government review and approval. The body of the specification takes precedence in the event of a conflict with the VCRM. Verification methods identified in the VCRM, and to be used in the EVCRM, are defined in the following subsections. 4.2.1 Inspection (I) Inspection is a method of verification of the physical characteristics by examination of the equipment and associated documentation. Inspections are conducted with the use of inspection tools, measurement devices, visual means, and comparison. Most inspections apply to verification of requirements associated with physical characteristics such as size, weight, and appearance; adherence to specified standards and engineering practices; and construction supported with quality documentation. 4.2.2 Analysis (A) Analysis is a method of verification through technical evaluation of calculations, computations, models, and analytical solutions; use of studies; reduced data; and/or representative data to determine that the item conforms to the specified requirements of Section 3. 4.2.3 Demonstration (D) Demonstration is a method of verification whereby the properties, characteristics, and parameters of the item are determined by observation alone, and without the use of instrumentation for quantitative measurements. This is used when a Section 3 requirement does not contain a specific numerical parameter that must be measured. Pass/fail criteria are simple accept/reject indications of functional performance since no quantitative values are specified. 4.2.4 Test (T) Test is a method to verify that a specified requirement is met by thorough exercising of the applicable item under specified conditions and using appropriate instrumentation IAW test procedures. This method is used when it is possible to make direct or indirect measurement of a specific numerical parameter to verify compliance with a Section 3 requirement. Actual measured values are recorded, and pass/fail is determined by comparing the measured value with the specified value.

APPENDIX B Definitions of Terms

Accuracy: The degree of conformity of a measured or calculated value to its definition, related to the offset from an ideal value. Acq or Acquisition: The point at which performance evaluation test equipment achieves synchronization with a signal from a communications satellite

Acq & Sync Reference ES/N0: The threshold ES/N0, as specified for back-to-back -4 BER performance, that corresponds to a BER of 10 . If a threshold ES/N0 is not specified for back-to-back error performance of BER = 10-4, then the reference ES/N0 is extrapolated from the threshold ES/N0 of the highest specified BER point at a rate of -0.05 dB of ES/N0 per BER factor of 10. Agent [SNMPv3]: Device subject to control. The EDIM Modem is the SNMPv3 agent. Aggregate: An IF waveform comprised of component channels. Aggregates include DCS waveforms as well as combined WSP waveforms. Atomic transaction: An indivisible and irreducible series of database operations such that either all occur, or nothing occurs. I.e. other users are locked out while one user reads and writes a group of interrelated parameters. This way parameters in that group don’t change in the middle of a read. A guarantee of atomicity prevents updates to the database occurring only partially, which can cause greater problems than rejecting the whole series outright. Back to back: Refers to Intermediate Frequency (IF) testing of modems in which two identical modems are used with adequate physical separation to prevent any interaction beyond IF connectivity. Bit Error Ratio (BER): The number of bit errors divided by the total number of transferred bits during a specified time interval. Certification: the acknowledgment that a validation has been completed and the criteria established by the certifying organization for issuing a certificate has been met. Channel: An IF waveform subject to combination or resulting from division. Channels include LMA waveforms as well as divided WSP waveforms. COMSEC (Communications Security): Encryption used to protect IP payload messages. The EDIM Modem is intended to transport COMSEC encrypted data traffic. Configure: to set up for operation in a particular way with a view to a specific application, usage or mission.

B-1 EDIM Modem Solicitation # W52P1J-21-R-0001 Section 4: System Specification 30 Sept 2020

Cover [Encryption]: Encryption used to protect IP headers to prevent exploitation of traffic patterns. The EDIM Modem can be configured to provide cover through its modem emulations. The default configuration is for cover to be enabled. Data Link Layer: Layer 2 in the Open Systems Interconnection (OSI) Model. The data link layer provides node-to-node data transfer, i.e. a link between two directly connected nodes. It detects and possibly corrects errors that may occur in the physical layer. It defines the protocol to establish and terminate a connection between two physically connected devices. It also defines the protocol for flow control between them.

Data rate (RD): The rate at which data traffic, incident upon one or more data interfaces, is transferred across a satellite channel, measured in bits per second (bits/s). dBC: Ratio of a non-carrier power component to the total power in a carrier, expressed in decibels. Digital IF: A digital waveform medium where waveforms are digitally sampled and presented in a predetermined format.

Eb/N0 The ratio of energy per bit to noise Power Spectral Density (PSD) . Converts from ES/N0 using

퐸 푅 퐸 b = S × S 푁0 푅D 푁0

Error Vector Magnitude (EVM): Sometimes referred to as “constellation error” (CE), EVM is a measurement used to quantify the performance of a digital radio transmitter. EVM is expressed in percent Root Mean Square (RMS) and is computed as follows.

1 NS − 1 2 √ ∑ 퐸푉푀 (kS) N kS = 0 퐸푉푀 = S 1 NC − 1 2 2 √ ∑ 퐼ref (kC) + 푄ref (kC) NC kC = 0 where: NS = the number of symbols over which the EVM measurement is taken; kS = the symbol index; mod NC = the number of constellation points in the modulation waveform = 2 index; kC = the constellation point index; 퐼ref(kC) = in-phase coordinate of kc indexed ideal constellation point; 푄ref(kC) = quadrature-phase coordinate of kc indexed ideal constellation point.

B-2 EDIM Modem Solicitation # W52P1J-21-R-0001 Section 4: System Specification 30 Sept 2020 and

2 2 퐸푉푀(kS) = √퐼err (kS) + 푄err (kS)

where: 퐼err(kS) = 퐼actual(kS) − 퐼ref(kS); 퐼actual(kS) = in-phase coordinate of kS indexed actual constellation point; 푄err(kS) = 푄actual(kS) − 푄ref(kS); 푄actual(kS) = quadrature coordinate of kS indexed actual constellation point.

ES/N0: The ratio of energy per symbol to noise PSD. Converts from Eb/N0 using

퐸 푅 퐸 S = D × b 푁0 푅S 푁0

Flow: a unidirectional stream of packets from a specific source to a specific destination. Frequency uncertainty: The difference between a received signal’s expected frequency and its actual frequency. Frequency uncertainty results when 1) a difference in frequency between reference oscillators exists, 2) Doppler effects cause frequency shifts, or 3) frequency setting inaccuracies exist. Infant mortality: Early life failure. Failure of equipment within the first six months of deployment. MAC address: Short for “Media Access Control” address – a hardware address that uniquely identifies each node of a network. Manager [SNMPv3]: Device controlling the agent. Any M&C device imposing control over the EDIM Modem is its SNMPv3 manager. Mod-cod: Specific combination of modulation format (mod) and code rate (cod). Modem emulation: A standardized or otherwise prescribed set of rules governing the signal processing and waveform construction required to produce a conforming modulation waveform. Conformance to specified modem emulations is the basis for waveform-level interoperability between modems. Packet Channel: A bidirectional traffic channel provided for transport of encapsulated Ethernet Frames.

QEF ES/N0: The threshold ES/N0, as specified for back-to-back BER performance, -10 that corresponds to a BER of 10 . If a threshold ES/N0 is not specified for back- -10 to-back error performance of BER = 10 , then the reference ES/N0 is extrapolated

B-3 EDIM Modem Solicitation # W52P1J-21-R-0001 Section 4: System Specification 30 Sept 2020

from the threshold ES/N0 for the lowest specified BER point at a rate of +0.05 dB -1 of ES/N0 per BER factor of 10 . SATCOM Gateway: Strategic entry point for terrestrial data traffic into SATCOM communications link and for SATCOM data traffic to terrestrial distribution. [Digital IF] Sink: A Digital IF stream origination point identified by a network IP address and port. [Digital IF] Source: A Digital IF stream origination point identified by a network IP address and port. Stability: The degree of conformity of a measured or calculated value to its original value at the beginning of some prescribed time interval, related to the offset from a prior state. Strategic SATCOM Enterprise: Aggregated SATCOM resources for widespread DoD use.

Symbol rate (RS): The rate at which symbols are transferred across a satellite channel, measured in symbols per second (sym/s). Throughput: The number of bits, frames or packets per second passing through an interface or device. The ITA throughput rate changes in response to changing link conditions. This in turn changes the Packet Channel rate in scenarios employing the Packet Channel.

Threshold Eb/N0: The Eb/N0 at which the measured BER must not exceed the specified BER. Threshold Eb/N0 = threshold ES/N0 × RS/RD. Utilization: The percent of a resource that is in use. Packet Channel utilization refers to the percent of the Packet Channel rate that is carrying traffic plus overhead. Validation: the process of testing implementations for conformance. The validation process consists of the steps necessary to perform the conformance testing by using an official test suite in a prescribed manner. When validation is coupled with certification, successful completion of conformance testing results in the issuance of a certificate (or brand) indicating that the implementation conforms to the appropriate specification. It is important to note that certification cannot exist without validation, but validation can exist without certification. Similarly, validation cannot exist without conformance testing (i.e., a test suite), but conformance testing can be performed without validation.

APPENDIX E Derivations of Digital IF Performance Thresholds

This appendix supplies derivations for various analytical Digital IF performance thresholds found in various subsections of 3.2.5.1.7”

E.1 Background Derivations The following derivations are developed as background for subsequent derivations. Carrier amplitude in dB begins with full scale amplitude; “full scale” being “+FS” to “-FS” as illustrated below.

Peak/average ratio is subtracted WRT FS for average envelope. 3 dB is then subtracted from average envelope to yield RMS carrier level C.

peak 퐶 = − | − 3.01 dBFS (1) avg dB

Noise amplitude is ESym/N0 below carrier amplitude as illustrated below.

̅̅̅̅̅̅̅̅2̅ Now consider RMS sampling error √휖Samp as follows.

Start with RMS sampling error of either component, real or imaginary. The illustration below shows the case of digitization between ± full scale (±FS).

2Nbits number of levels are depicted at a spacing of 21−Nbits FS. Digitization 1−Nbits (sampling) error 휖Samp may vary from – ½ to + ½ of this 2 FS spacing. This −Nbits 휖Samp error range is depicted in the illustration as ±2 FS.

2 Digitization noise energy per sample is the square of RMS sampling error 휖Samp .

̅̅̅̅̅̅̅̅2̅ It therefore makes sense to evaluate the RMS sampling error √휖Samp .

Parentheticals will now be used to point out components of the corresponding

̅̅̅̅̅̅̅̅2̅ equation below. This RMS sampling error √휖Samp (left side) is evaluated (right side) as the square root (radical) of the average power (integral of 푥2 over a unit interval of 푥) evaluated over ± ½ (integration limits, a unit interval of 푥) of the

digitization level spacing 21−Nbits FS (brought out as a coefficient). This is first expressed

1 2 ̅̅̅̅̅̅̅̅2̅ 1−N 2 √휖Samp = 2 bits FS √∫ 푥 푑푥 1 −2

and is then evaluated

1 1 2 ̅̅̅̅̅̅̅̅2̅ −N 3 √휖Samp = 2 × 2 bits FS√ [ 푥 ] 3 1 −2

1 1 1 = 2 × 2−Nbits FS√ [ ( − − )] 3 8 8

1 1 = 2 × √ × 2−Nbits FS 3 4

1 = √ 2−Nbits FS 3

resulting in

1 2 1 √휖̅̅̅̅̅̅̅̅2̅ = 21−Nbits FS √ ∫ 푥2 푑푥 = √ 2−Nbits FS (5) Samp 1 3 −2

Square each side for average power

Multiply by two to account for real and imaginary components. Divide the result by the complex sampling rate RSamp for digital sampling error PSD NSamp

2 ̅̅̅̅̅̅̅̅2̅ 2−2 Nbits FS 2 휖Samp 3 푁Samp = = 푅Samp 푅Samp

Logarithmically, as illustrated below,

푁Samp = −1.76 − 6.02 Nbits − 10 log10(푅Samp) dBFS/Hz (6)

Whereas linearly, digitization noise power NDig affecting demodulation of a carrier with symbol rate RSym is

푁Dig = 푁Samp 푅Sym

Logarithmically, NDig power is

푁Dig = −1.76 − 6.02 Nbits − 10 log10(푅Samp) + 10 log10(푅Sym) dBFS

E-5 EDIM Modem Solicitation # W52P1J-21-R-0001 Section 4: System Specification 30 Sept 2020

or

푅Samp 푁Dig = −1.76 − 6.02 Nbits − 10 log10 ( ) dBFS (7) 푅Sym

E.2 Derivation of Digital IF Noise PSD This derivation addresses Digital IF digitization noise PSD requirements beginning in 3.2.5.1.7.3.

Start with sampling noise PSD 푁Samp in terms of • sample size Nbits • complex sample rate 푅Samp • normalized to full scale digitizing amplitude “FS”

푁 | = −1.76 − 6.02 N − 10 log (푅 ) [dB ] Samp FS bits 10 Samp FS/Hz (6)

Then recognize total digitally sampled power 푃Ʃ, again normalized to full scale digitizing amplitude “FS,” in a system with functional AGC driving peak levels close to full scale (FS), can be reasonably bounded by

푃Ʃ|FS ≥ −19.76 [dBFS/Hz] = −3 − 14 − 2.76 [dBFS] where • -3 dB is the power of a sinusoid of full scale amplitude on one I-Q axis • 14 dB is a liberal peak to average ratio for the sum of many random carriers, where the Central Limit Theorem suggests Gaussian distributed waveform amplitude • 2.76 dB is offered as margin below full scale, with decimal places chosen to cancel those of the first 푁 | component Samp FS

The sampling noise PSD 푁Samp in terms of total digitally sampled power 푃Ʃ is therefore (logarithmically)

| 푁Samp| = 푁Samp| − 푃Ʃ FS [dB푃Ʃ/Hz] 푃Ʃ FS

Substitution yields

E-6 EDIM Modem Solicitation # W52P1J-21-R-0001 Section 4: System Specification 30 Sept 2020

푁Samp| ≤ 18 − 6.02 푁bits − 10 log10(푅Samp) [dB푃Ʃ/퐻푧] 푃Ʃ

E.3 Derivation of Realizable Digital IF Spectral Selectivity This derivation addresses Digital IF spectral mask requirements found in 3.2.5.1.7.4 and in FIGURE 13.

Start with sampling noise PSD NSamp in terms of • sample size Nbits • complex sample rate 푅Samp • normalized to full scale digitizing amplitude “FS”

푁 | = −1.76 − 6.02 N − 10 log (푅 ) [dB ] Samp FS bits 10 Samp FS/Hz (6)

Now consider digitally sampled single-carrier power 푃C, again normalized to full scale digitizing amplitude “FS”

푃C|FS ≥ −17.76 [dBFS/Hz] = −3 − 12 − 2.76 [dBFS] where • -3 dB is the power of a sinusoid of full scale amplitude on one I-Q axis • 12 dB is a liberal peak to average ratio for a carrier of high modulation order • 2.76 dB is offered as margin below full scale, with decimal places chosen to cancel those of the first 푁 | component Samp FS

The sampling noise PSD 푁Samp in terms of total digitally sampled power 푃C is therefore (logarithmically)

| 푁Samp| = 푁Samp| − 푃C FS [dB푃C/Hz] 푃C FS

Substitution yields

푁Samp| ≤ 16 − 6.02 Nbits − 10 log10(푅Samp) [dB푃C/Hz] 푃C

E-7 EDIM Modem Solicitation # W52P1J-21-R-0001 Section 4: System Specification 30 Sept 2020

Consider now that carrier power spectral density 푃푆퐷C is related to carrier power 푃C by

푃푆퐷C = 푃C − 10 log10(푅Sym) where 푅Sym is the carrier symbol rate. This can also be expressed

| 푃푆퐷C 푃C = − 10 log10(푅Sym)

Whereas, logarithmically,

| 푁Samp| = 푁Samp| − 푃푆퐷C 푃C [dB] 푃푆퐷C 푃C

| Substitution for 푁Samp| and for 푃푆퐷C 푃C yields 푃C

푁Samp| ≤ 16 − 6.02 Nbits − 10 log10(푅Samp) + 10 log10(푅Sym) [dB] 푃푆퐷C or

푅Samp 푁 | ≤ 16 − 6.02 N − 10 log ( ) [dB] Samp 푃푆퐷 bits 10 C 푅Sym

For minimum selectivity, substituting

푅Samp = 푅Sym yields

limit of 푁Samp| ≤ 16 − 6.02 Nbits [dB] 푃푆퐷C

In the case of 16 bits per sample, maximum PSD discrimination would reasonably exceed (6 × 16 - 16 =) 80 dB.

For maximum selectivity, substituting

E-8 EDIM Modem Solicitation # W52P1J-21-R-0001 Section 4: System Specification 30 Sept 2020

• A minimum complex sampling rate of 109 complex samples per second for 푅Samp 3 • A minimum symbol rate of 256 × 10 symbols per second for 푅Sym yields a spectral confinement selectivity limit of

109 limit of 푁Samp| ≤ 16 − 6.02 Nbits − 10 log10 ( 3) [dB] 푃푆퐷C 256 × 10 which simplifies to

limit of 푁Samp| ≤ 16 − 6.02 Nbits − 36 [dB] 푃푆퐷C and

limit of 푁Samp| ≤ − 6.02 Nbits − 20 [dB] 푃푆퐷C

In the case of 16 bits per sample, maximum PSD discrimination would reasonably exceed (6 × 16 + 20 =) 116 dB.

E.4 Digital IF EVM Threshold This derivation addresses the Digital IF EVM requirements beginning in 3.2.5.1.7.5.

Start with digitization noise power 푁Dig within the carrier spectrum in terms of • sample size Nbits • complex sample rate 푅Samp • symbol rate 푅Sym • normalized to full scale digitizing amplitude “FS”

푅Samp 푁 | = −1.76 − 6.02 N − 10 log ( ) dB (7) Dig FS bits 10 FS 푅Sym

Recognize now that total digitally sampled power 푃Ʃ , again normalized to full scale digitizing amplitude “FS,” in a system with functional AGC driving peak levels close to full scale (FS), can be reasonably bounded by

E-9 EDIM Modem Solicitation # W52P1J-21-R-0001 Section 4: System Specification 30 Sept 2020

푃Ʃ|FS ≥ −19.76 [dBFS] = −3 − 14 − 2.76 [dBFS] Hz where • -3 dB is the power of a sinusoid of full scale amplitude on one I-Q axis • 14 dB is a liberal peak to average ratio for the sum of many random carriers, where the Central Limit Theorem suggests Gaussian distributed waveform amplitude • 2.76 dB is offered as margin below full scale, with decimal places chosen to cancel those of the first 푁 | component Samp FS

Recognize now that total carrier power 푃Ʃ|FS is the sum of carrier powers 퐶|FS, any of which can be expressed logarithmically as

퐶|FS ≥ 퐶 − 푃Ʃ − 19.76 [dBFS/Hz]

The ratio of digital sampling noise power 푁Dig to carrier power 퐶 can be expressed logarithmically

푁 | − 퐶| Dig FS FS 푅Samp ≤ − 1.76 − 6.02 Nbits − 10 log10 ( ) 푅Sym − (푃C − 푃Ʃ − 19.76) [dB]

Which reduces to

푅Samp 푁Dig − 퐶 ≤ 18 − 6.02 Nbits − 10 log10 ( ) + (푃Ʃ − 퐶) [dB] 푅Sym

This can be converted to a linear amplitude ratio

푅 Samp ( ) 18 − 6.02 Nbits − 10 log10( 푅 ) + 푃Ʃ−퐶 푁Dig Sym EVM = √ ≤ 10 20 푃C

where

E-10 EDIM Modem Solicitation # W52P1J-21-R-0001 Section 4: System Specification 30 Sept 2020

푁 √ Dig is the square root of the ratio of digitization noise power 푁 within the 퐶 Dig spectrum of the COI and COI power 퐶

Nbits is the number of bits per sample in the digitization process

푅Sym is the carrier symbol rate in symbols per second

푃Ʃ − 퐶 is the difference, in dB, between total digitized signal power 푃Ʃ and COI power 퐶 when both are expressed in dBm

EVM is customarily expressed in percent

APPENDIX F Modem Waveform Selection and BER Performance

This appendix supplies rationale and explanations for selection of the EBEM waveform IAW 3.2.5.1.2, specifically 3.2.5.1.2.4, and for mod-cod selection and BER performance thresholds found in the subsections of 3.2.5.1.5.7 “LM Back-to- Back BER” and 3.2.5.1.8.6 “DM Back-to-Back BER,” specifically TABLE III

F.1 Emulation Selection An EBEM emulation was selected to the exclusion of DVB-S2X with the following rationale. 1. EBEM mod-cods span the range anticipated for WGS operation 2. DVB-S2X power efficiency advantages appear to be significant at higher mod-cods, but not so much so at the lower mod-cods more appropriate to operation over present WGS systems 3. Higher data traffic rates achievable through DVB-S2X may also be achieved by extending maximum EBEM data traffic and symbol rates 4. Development and functional standardization of DVB-S2X provisions for cryptographic data traffic cover appears prohibitive in scope It appears more practical to defer DVB-S2X emulation implementation to a possible future upgrade.

F.2 EBEM Mod-Cods Mod-cods required in 3.2.5.1.2 “NATO STANAG 4486 Ed4 (EBEM),” and more specifically in 3.2.5.1.2.4 “Waveform” and as indicated in TABLE III, were selected as follows. • Typical EBEM BER performance was taken from a 2017 MD-1366 datasheet found at https://www.viasat.com/sites/default/files/media/documents/ebem_md- 1366_045_web.pdf • The 20 EBEM mod-cods, BPSK through 16-APSK rates 1/2 through 19/20, were tabulated with their spectral efficiencies and typical Eb/N0 performance corresponding to BER=10-8 • The 20 EBEM mod-cods were then sorted by spectral efficiency. • Mod-cods were pruned where Eb/N0 performance did not descend uniformly with spectral efficiency

F-1 EDIM Modem Solicitation # W52P1J-21-R-0001 Section 4: System Specification 30 Sept 2020

8-PSK 2/3 and 16-APSK 1/2 have identical spectral efficiencies (~2 bps/Hz) but the performance distinction was clear. QPSK 3/4 and 8-PSK 1/2 have identical spectral efficiencies (~1.5 bps/Hz) and -8 their typical 10 BER Eb/N0 performance is also identical (3.05 dB). QPSK 3/4 was chosen because 1. Typical performance differences between 10-6 and 10-8 suggest better BER flare-out performance beyond 10-8 2. Published specified thresholds are also tied at 10-10 but slightly favor QPSK 3/4 at 10-6 and 10-8 BPSK 1/2 was retained because 1. Its performance is typically just slightly better than that of QPSK 2. Its significantly lower spectral efficiency is useful to reduce out of band radiated power flux densities when used with VSAT terminals. In which case Enterprise Gateway terminals would need to receive it. F.3 EBEM BER Performance EBEM emulation BER performance thresholds specified in 3.2.5.1.5.7 “LM Back- to-Back BER” and in 3.2.5.1.8.6 “DM Back-to-Back BER” as indicated in TABLE III were selected as follows. • Typical EBEM BER performance was taken from a 2017 MD-1366 datasheet found at https://www.viasat.com/sites/default/files/media/documents/ebem_md- 1366_045_web.pdf • Digital IF performance thresholds were computed by adding 0.5 dB to these typical values • L-Band performance thresholds were computed by adding another o 0.35 dB to BPSK waveform BER performance thresholds o 0.40 dB to QPSK waveform BER performance thresholds o 0.45 dB to 8-PSK waveform BER performance thresholds o 0.50 dB to 16-APSK waveform BER performance thresholds • All these values apply to 16,384 bit Turbo Code block sizes. Other Turbo Code block sizes are granted threshold allowances of o 0.8 dB for 4096 bit blocks o 1.6 dB for 1024 bit blocks
