    Abstract: the AF relaying system based on the maximum likelihood criterion. Since the optimum combining rule depends on the channel gains of the relay-to-destination links which are usually unavailable in the context of differential modulation, we propose a suboptimal diversity combining rule which replaces the instantaneous channel gains by their second order statistics. Compared with the performance of the diversity combining rule without taking the time-selectivity into account, computer simulation results show that the proposed diversity combining rule has superior performance for the AF relaying system in time-selective Rayleigh fading channels, especially when the relay and destination nodes have different Doppler spreads.
