MULTILEVEL SEQUENCES AND LINE CODES by LOUIS BOTHA Thesis submitted as partial fulfilment of the requirements for the degree MASTER OF ENGINEERING in ELECTRICAL AND ELECTRONIC ENGINEERING in the FACULTY OF ENGINEERING at the RAND AFRIKAANS UNIVERSITY SUPERVISOR: PROF HC FERREIRA MAY 1991 SUMMARY As the demand for high-speed data communications over conventional channels such as coaxial cables and twisted pairs grows, it becomes neccesary to optimize every aspect of the communication system at reasonable cost to meet this demand effectively. The choice of a line code is one of the most important aspects in the design of a communications system, as the line code determines the complexity, and thus also the cost, of several circuits in the system. It has become known in recent years that a multilevel line code is preferable to a binary code in cases where high-speed communications are desired.

  • Digital Data Transmission Unit 3
    Unit 3 Digital Data Transmission What is Line Coding? The input to a digital system is in the form of sequence of digits. The input can be from the sources such as data set, computer, digitized voice (PCM), digitalTV orTelemetry equipment. Line coding is the process in which the digital input is coded into electrical pulses or waveforms for the transmission over channel. Regenerative Repeaters are used at regular intervals along a digital transmission line to detect the incoming digital signal and to transmit the new clean pulse for the further transmission along the line. Line Coding Line Coding There are many ways of assigning pulses (waveforms) to the digital data. For example a high voltage level (+V) could represent a “1” and a low voltage level (0 or -V) could represent a “0”. Line Coding-Examples Line Coding Signal element versus Data element Data element (1s & 0s) are what we need to send and signal elements (+V & -V voltages) are what we can send. Data elements are being carried and signal elements are the carriers. The data rate defines the number of bits sent per sec - bps. It is often referred to the bit rate. The signal rate is the number of signal elements sent in a second and is measured in bauds. Line Coding Line Coding Requirements Small transmission bandwidth Power efficiency: as small as possible for required data rate and error probability Error detection/correction Timing information: clock must be extracted from data Transparency: all possible binary sequences can be transmitted. LINE CODING Unipolar NRZ All signal levels are on one side of the time axis - either above or below.

  • Digital & Analog Transmission
    Chapter 4: Digital Transmission (Line coding, Block coding, Scrambling) Digital to digital conversion (Line Coding) Converting a sequence of data bits (text, numeric, audio, or video) into a digital signal, at the sender, then recovering the original bit sequence from the signal, at the destination data rate ≡ bit rate(N) b/s, signal rate(S) ≡ baud ratechange/s (Hz) Let r bit/change, Nmax = S * r * 1/c where c is and usually assumed ½ For the average calculations of S&N The goal is to increase the data rate (information flow) while decreasing band rate (better utilization of channel BW, cheaper links) Factors to consider in digital signaling: Long strings of 0’s or 1’s causes a drift of the obtained baseline, hence “baseline wandering” that leads to incorrect bit decoding. 1) Baseline wandering: The receiver averages the signal power (Baseline), and uses it to decode the received signal bit value. 2) DC components: Constant level for long period of time creates very low frequency components in the frequency spectrum, that might not pass through some medium (e.g., TP of 200Hz 3000Hz). Hence, we need to remove the DC from the Digital Signal . 3) Self-Synchronization: To match the sender and receiver clocks, hence match the bit intervals at both ends for correct decoding. Transitions in the digital signal act as self-synch altering the receiver to the start, mid, or end of the bit, resetting its clock in case it is out of synch. 4) Built in error detection: It is good to add extra bits to the Tx data for error detection (and possibly correct).
