摘要：

A direct sequence/binary differential phase-shift keying underwater acoustic communication technique based on differential coherent demodulation is proposed.Differential coherent demodulation is adopted at the receiving terminal to overcome the difficulty of estimating the carrier in underwater acoustic communication and overcoming the frequency and phase error resulting from carrier frequency drift.Anti-multipath,antiDoppler,low-error-rate,effective and robust features for a complex underwater acoustic channel were verified in a lake experiment.
