A method for underwater acoustic communication includes steps of S1: capturing a synchronization signal using a replica correlation operation; S2: performing time reversal forward shift processing and time reversal backward shift processing, respectively, on the synchronization signal to obtain a forward shift time reversal coefficient and a backward shift time reversal coefficient; S3: performing a convolution operation of the forward shift time reversal coefficient and the backward shift time reversal coefficient, respectively, with a subsequently captured information sequence to obtain a forward shift time reversal output and a backward shift time reversal output; S4: processing the forward shift time reversal output and the backward shift time reversal output, respectively, with a forward shift equalizer and a backward shift equalizer to obtain two sets of equalizer outputs; and S5: selecting one of the two sets of equalizer outputs with a smaller error for data decoding to obtain a desired signal.
