  • Spectral Efficiency and BER Analysis in 802.16E Standard
    Spectral Efficiency and BER Analysis In 802.16e Standard A thesis submitted in partial fulfilment of the requirements for the award of the Degree of MASTER of ENGINEERING in ELECTRONICS AND COMMUNICATION ENGINEERING Submitted by: SHYAM PRATAP SINGH Roll No. 800861013 Under the guidance of: Dr. KULBIR SINGH Assistant Professor, ECED DEPARTMENT OF ELECTRONICS AND COMMUNICATION ENGINEERING THAPAR UNIVERSITY PATIALA-147004, Punjab, INDIA. June 2010 ABSTRACT Spectrum being nature’s gift; needs most wise use of it. OFDM system is an excellent way to utilize the spectrum. OFDM is a parallel data transmission system which promises the high data rate with minimum degradation of the quality of service relative to serial communication techniques. In OFDM, a single channel utilizes multiple sub-carriers on adjacent frequencies. In addition the sub- carriers in an OFDM system are overlapping to maximize spectral efficiency. Ordinarily, overlapping adjacent channels can interfere with one another. However, sub-carriers in an OFDM system are precisely orthogonal to one another. Thus, they are able to overlap without interfering. As a result, OFDM systems are able to maximize spectral efficiency without causing adjacent channel interference. In order to obtain the orthogonality the subcarrier frequencies must be spaced by a multiple of the inverse of symbol duration. Other than spectral efficiency OFDM has many advantages, as immunity to impulse interference, resilient to RF interference, robustness to channel fading, resistance to multipath, much lower computational complexity(collectively, they reduces bit error rate ). Also, WiMAX being one of the standards which is using OFDM, has excellent spectral efficiency but there are no limits for researcher’s, that is inspiration for “spectral-efficiency and BER analysis in 802.16e”.

  • Hybrid Adaptive Bias OFDM-Based IM/DD Visible Light Communication System
    hv photonics Article Hybrid Adaptive Bias OFDM-Based IM/DD Visible Light Communication System Huandong Hong † and Zhengquan Li *,† Jiangsu Provincial Engineering Laboratory of Pattern Recognition and Computational Intelligence, Jiangnan University, Wuxi 214122, China; [email protected] * Correspondence: [email protected]; Tel.: +86-138-6183-7081 † These authors contributed equally to this work. Abstract: Conventional optical orthogonal frequency division multiplexing (OFDM) schemes, such as adaptively biased optical OFDM (ABO-OFDM) and hybrid asymmetrically clipped optical OFDM (HACO-OFDM), are unable to tap all the resources of the subcarriers and only achieve relatively high power efficiency. In this paper, a hybrid adaptive bias optical OFDM (HABO-OFDM) scheme for visible light communication (VLC) is proposed to improve spectral efficiency and power efficiency. In the proposed HABO-OFDM scheme, different optical OFDM components are combined for transmission at the same time, and the adaptive bias is designed to ensure the non-negativity, as well as obtaining significantly high power efficiency. Meanwhile, the implementation complexity of the HABO-OFDM receiver is notably lower than the conventional superimposed optical OFDM schemes. Simulation results show that the proposed HABO-OFDM scheme outperforms ABO-OFDM and HACO-OFDM in terms of both peak-to-average-power ratio (PAPR) and power efficiency. The PAPR performance of HABO-OFDM is about 3.2 dB lower than that of HACO-OFDM and 1.7 dB lower than that of ABO-OFDM. Moreover, we can see that the Eb(elec)/N0 required for HABO-OFDM to reach the BER target is lower than the other two schemes at the Bit rate/Normalized bandwidth range of 3.5 to 8.75, which means that the power efficiency of HABO-OFDM is higher in this range.

  • Increasing Spectral Efficiency in Wifi6 Networks Using OBSS/PD
    1 More WiFi for Everyone: Increasing Spectral Efficiency in WiFi6 Networks using OBSS/PD Mechanism Ali Karakoc¸, Mehmet S¸ukr¨ u¨ Kuran, Member IEEE, and H. Birkan Yilmaz, Member, IEEE Abstract This study aims to enhance spatial reuse by using the new features of IEEE 802.11ax WLANs. Since the wireless medium is a shared medium and there may be multiple basic service sets (BSS) in the same vicinity, BSSs may overlap, and interference occurs. In this situation, BSSs cannot transmit simultaneously due to the exposed node problem. The IEEE 802.11ax standard has a couple of mechanisms to resolve these spectral efficiency problems. One of the most effective mechanisms that address these problems is the overlapping BSS preamble detection (OBSS/PD) mechanism. OBSS/PD mechanism uses the color mechanism to distinguish OBSS signals. By using a signal threshold, the mechanism can ignore some of the signals, which cause interference. In this paper, we propose a rate-adaptive dynamic OBSS/PD threshold algorithm that tracks the changes in transmission rate and dynamically adjusts the threshold step by step considering the changes. I. INTRODUCTION HIS paper focuses on the WiFi standard IEEE 802.11ax and its features related to spatial reuse. Among the various features T being proposed in WiFi6, one of them is the OBSS-PD mechanism. In dense environments, if there are overlapping BSSs using the same channels, the traffic belonging to these BSSs must share the channel and contend for access. Before performing the transmission, each node should check whether the medium is in an idle state or not.

  • CU-LTE: Spectrally-Efficient and Fair Coexistence Between LTE and Wi
    CU-LTE: Spectrally-Efficient and Fair Coexistence Between LTE and Wi-Fi in Unlicensed Bands Zhangyu Guan and Tommaso Melodia Department of Electrical and Computer Engineering Northeastern University, MA 02115, USA Email:fzguan, [email protected] Abstract—To cope with the increasing scarcity of spectrum the radio resource management (RRM) schemes used by LTE resources, researchers have been working to extend LTE/LTE- and by systems already deployed in unlicensed band (e.g., A cellular systems to unlicensed bands, leading to so-called Wi-Fi). The underlying RRM policy of LTE systems is in unlicensed LTE (U-LTE). However, this extension is by no means straightforward, primarily because the radio resource fact based on centralized scheduling on each LTE base station management schemes used by LTE and by systems already (referred to as eNodeB). This is different from typical systems deployed in unlicensed bands are incompatible. Specifically, it with distributed control that are already deployed in unlicensed is well known that coexistence with scheduled systems like LTE bands, e.g., IEEE 802.11-based (Wi-Fi) systems with RRM degrades considerably the throughput of Wi-Fi networks that are based on distributed coordination function (DCF) running in based on carrier-sense medium access schemes. To address this challenge, we propose for the first time all wireless stations (STAs). It has been observed that the a cognitive coexistence scheme to enable spectrum sharing throughput of Wi-Fi systems can be considerably degraded between U-LTE and Wi-Fi networks, referred to as CU-LTE. (more than 50% under high traffic loads) in the presence of The proposed scheme is designed to jointly determine dynamic co-channel interference from LTE systems [3], [4], which is channel selection, carrier aggregation and fractional spectrum not desirable especially for SPs who have deployed tens of access for U-LTE networks, while guaranteeing fair spectrum access for Wi-Fi based on a newly designed cross-technology thousands of Wi-Fi hotspots over the world.
