1. 6. PERFORMANCE ANALYSIS OF MULTIPLE ANTENNA TECHNIQUES IN WiMAX

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Yousaf Ali Shah; [2010]
   Nyckelord :WiMAX; Capacity Analysis; STBC; MIMO; SFBC;

   Sammanfattning : The modern wireless systems are required to have high voice quality and data rate. Since our concern is most with cattering environment, antenna diversity is a practically effective and widely applied technique to reduce the effect of multipath fading. LÄS MER

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Muhammad Hassan; Abdul Sattar; [2010]
   Nyckelord :MIMO-OFDM; STBC; WIMAX; etc;

   Sammanfattning : The demand of different multimedia services and different internet supported applications on mobile devices requires a high speed data rate and good service of quality. This can be obtained by implementing multiple Antenna technology on both stations i.e. LÄS MER

4. 8. A study of closed loop space time block coding techniques for MIMO-OFDM

   Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandling

   Författare :Shabbar Ali Khan; [2006]
   Nyckelord :closed loop space time block coding;

   Sammanfattning : In this dissertation, the STBC-OFDM technique is therefore investigated in order to improve the bit error rate performance of such wireless communication systems speci¯cally those using multiple transmitter and receiver antennas.An investigation is undertaken of STBC with two transmit and one receive antennas as proposed by Alamouti together with quasi-orthogonal STBC with four transmit and one receive antennas.
