摘要：
The main limitations of wireless transmission are fading and associated reduction in bit error rate. To mitigate these effects several techniques are employed. One method is to employ multiple input multiple output (MIMO) systems. This paper presents performance analysis and a comparative study of different Space Time Block Codes over Rayleigh fading channel of a MIMO system. MIMO systems employing different modulation schemes with different code rates and maximum likelihood detection techniques at the receiver end are explored. Zero mean complex Gaussian random variables are taken as noise samples. Performance of Space Time Block codes with modulation techniques QPSK, 8PSK and 16PSK are investigated in terms of bit error rate under different SNR scenarios.
