| Summary: | Utilizing channel correlation and time-varying fading parameter,a novel optimal noncoherent receiver for dif-ferential space-time modulation in correlated time-varying fading channels was derived.Under several special channels,the optimal receiver was simplified.Based on the decision feedback data,a suboptimal noncoherent receiver named DF-NCR was presented for the application of the optimal receiver.Analysis and simulation results show that the error performance of differential space-time modulation system with the proposed DF-NCR is better than conventional differ-ential transmission method in correlated time-varying fading channels. |
