  1. 1. Time Synchronization for Full-Duplex Communications

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Ziyu Liu; Aamer Al-Hamwi; [2019]
    Keywords : Time Synchronization; In-band full-duplex; self-interference cancellation; Technology and Engineering;

    Abstract : In-band full-duplex has emerged as an attractive solution for significantly enhancing the throughput of wireless communication systems by doubling the spectrum efficiency compared to conventional half-duplex systems. However, the existence of self-interference is a significant barrier to operate full-duplex systems. READ MORE

  3. 2. Practical Aspects of Reduced Complexity LDPC Decoding using Forced Convergence

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Muhammad Umar Farooq; Maria Garcia Garcia; [2016]
    Keywords : LDPC; Forced Convergence; Decoding; OFDM; IEEE802.11; Technology and Engineering;

    Abstract : This thesis is an extension to the previous work done at Department of EIT in investigating the complexity reduction of LDPC decoding using the stochastic approximation method to improve the energy efficiency of energy-limited applica- tions, such as in mobile phones. The research carried out in this thesis investigates the complexity and conver- gence results of adaptive performance control algorithm (PCAA) that changes the forced convergence threshold in OMS LDPC FC decoding algorithm.

  4. 3. Fuzzy Based power control system Using ANFIS and MIMO-OFDM Techniques in Cognitive Radio Networks

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Mahesh Aleti; Rahamatulla Syed; Rajendra Prasad Chennupati; [2014]
    Keywords : Cognitive Radio; Power Control; the Fuzzy Interference System FIS ; ANFIS; “MIMO” “Multiple Input Multiple Output” ; “OFDM” “Orthogonal Frequency Division Multiplexing” ; AWGN; BER; SNR; Eb N0;

    Abstract : Cognitive Radio technology is used for efficient utilization of the spectrum. There are two types of users, one is the Primary user (PU), and the second one is the Secondary user (SU). In those users, PU is having the license to use the spectrum. The SU does not have the license to use the spectrum. READ MORE

  5. 4. Performance Evaluation of IEEE 802.16e (Mobile WiMAX) in OFDM Physical Layer

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Gazi Faisal Ahmed Jubair; Muhammad Imran Hasan; Md. Obaid Ullah; [2009]
    Keywords : WiMAX Performance;

    Abstract : WiMAX is introduced by the Institute of Electrical and Electronic Engineers (IEEE) which is standard designated 802.16d-2004 (used in fixed wireless applications) and 802.16e-2005 (mobile wireless) to provide a worldwide interoperability for microwave access. READ MORE

  6. 5. Performance study of IEEE 802.16d (Fixed WiMAX) Physical layer with Adaptive Antenna System

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Ahmer Ali Bajwa; Junaid Anwar Awan; [2008]
    Keywords : WiMAX IEEE 802.16d ; OFDM; Smart Antennas; AAS; LMS; Pre-FFT beamformer; SUI channel; Rician Fading; BER.;

    Abstract : In this thesis work, WiMAX (IEEE 802.16d) PHY layer with underlying OFDM technology and an optional feature called Adaptive Antenna System has been considered. The SUI-3 channel model (Rician fading) is used for creating fading phenomena. READ MORE
