An underwater communications system includes an antenna array, a sound transmission source for transmitting communication packets, and a receiver including a processor. The processor is programmed for receiving and detecting a Doppler-sensitive probe signal and training sequence, for estimating a channel impulse response function for correlating the received signal to yield a plurality of processed channel outputs, and for summing the channel outputs to yield a common receiver output. The common receiver output is applied to a Decision Feedback Equalizer (DFE) for adaptive correction of the inter-symbol interference and to retrieve the transmitted communication message.
