Abstract: In this study we have investigated the performance of space-time coding over flat rayleigh fading channel under different modulation schemes, such as BPSK, QPSK, 8-PSK and 16-QAM. It is shown by computer simulation that the performance of BPSK is the best among the 4-types and QPSK is better than 8-PSK and 8-PSK is better than 16-QAM.
