  1. 26. Applying OSTBC in Cooperative Cognitive Radio Networks

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Hamid Shahzad; Jaishankar Botchu; [2010]
    Keywords : Cognitive Radio; Cooperative Communication; OSTBC; Rayleigh Fading; Alamouti STBC; AF Relay; MRC; Energy Detector ;

    Abstract : In this report, we introduce cooperative spectrum sensing using orthogonal space time block coding (OSTBC) in order to achieve cooperative diversity in the cognitive radios (CRs) network. Transmit diversity or gain is achieved by introducing more than one antenna on the transmitter and receiver side, but in small electronic mobile devices it looks impractical. READ MORE

    Abstract : 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. READ MORE

  5. 29. PERFORMANCE ANALYSIS OF ADAPTIVE ARRAY SYSTEM AND SPACE-TIME BLOCK CODING IN MOBILE WIMAX (802.16e) SYSTEMS

    University essay from Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

    Author : Ngan Trieu Kim; Olumide Ajiboye; [2008]
    Keywords : WiMAX; 802.16e; Adaptive Antenna System ; Beamforming; MIMO; Space Time Coding ; AAS; STC;

    Abstract : We live in an information hungry age, we generate and process information at a rate never before recorded in the history of mankind. Today’s computing platforms are run on Gigahertz multi-core processors churning out Gigabits streams of data that need to be transmitted as quickly as possible. READ MORE

  6. 30. A study of closed loop space time block coding techniques for MIMO-OFDM

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Shabbar Ali Khan; [2006]
    Keywords : closed loop space time block coding;

    Abstract : 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.
