Abstract :
Differential space-time modulation (DSTM) proposed by [B.L. Hughes, Nov. 2000] has been proved that it does not need to change the modulation constellation and the implementation complexity is very low, compared with that given by Tarokh [July, 2000]. However, the performance of the DSTM over correlated Nakagami channels was not given. In this paper, we investigate it, where the correlated Nakagami channels given by Q.T. Zhang are employed. We first check the accuracy of the channel fading parameters and coefficient variations on the performance of DSTM.
