【Abstract】 Performance of differential space-time block coding (DSTBC) in Nakagami fading channel is analyzed. Encoding and decoding schemes of DSTBC with two transmitting antennas and one receiving antenna are presented. And based on above-mentioned, the bit error rate(BER) of DSTBC over Nakagami fading channel is deduced. Simulation results are consistent with theoretical values, which proves the correctness of the deduced expression of BER.更多还原
