摘要 In digital radio communication, diversity reception can combat flat fadingand adaptive equalization can combat Inter-Symbol Interference (ISI). In this paper, the structureand algorithm of a multi-channel equalizer with combined diversity reception and adaptiveequalization techniques are studied. Because Phase-Looked-Loops (PLL) are embedded in the equalizer,this equalizer is suitable for coherent communication in channels with high phase fluctuation.Monte Carlo simulation is used to test its performance and the results show that a multi-channeldecision-feedback-equalizer has better performance than a single-channeldecision-feedback-equalizer, and the results of processing high-speed digital underwatercommunication signals demonstrate this farther.
