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

    Master-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandling

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

    Sammanfattning : 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. LÄS MER

  5. 4. Efficient WiMAX Receiver Implementation on a Programmable Baseband Processor

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Christian Axell; Mikael Brogsten; [2006]
    Nyckelord :WiMAX; OFDM; Baseband; LeoCore;

    Sammanfattning : WiMAX provides broadband wireless access and uses OFDM as the underlying modulation technique. In an OFDM based wireless communication system, the channel will distort the transmitted signal and the performance is seriously degraded by synchronization mismatches between the transmitter and receiver.
