| Abstract | In this paper, performance of a Turbo coded wireless link is evaluated in the presence of Rayleigh fading for single-input single-output (SISO), single-input multiple-output(SIMO), multiple-input single-output (MISO) and multiple-input multiple-output (MIMO) system. Turbo encoded and 64-ary Quadrature Amplitude Modulation (QAM) modulated data are further encoded using space-time block coding (STBC) and then split into n streams which are simultaneously transmitted through single transmit antenna for Turbo-SIMO system and n transmit antennas for Turbo-MISO and Turbo-MIMO system. Simulation results obatianed show that the Turbo-SISO system provides 45 dB coding gain, Turbo-SIMO system provides 27,20 and 17 dB coding gain for 2,3 and 4 receive antenna respectively, Turbo-MISO system provides 26, 19 and 15 dB coding gain for 2,3 and 4 transmit antenna respectively, Turbo-MIMO system provides 12 to 17 dB coding gain for different combination of transmit and receive antennas at a BER of 10-6 compared to uncoded SISO, SIMO, MISO and MIMO system. |
