A method for underwater acoustic communication includes steps of S1: capturing a synchronization signal using a cross-correlation operation; S2: performing time forward shifting and reversing processing and time backward shifting and reversing processing, respectively, on the synchronization signal to obtain a forward shifted time reversal coefficient and a backward shifted time reversal coefficient; S3: performing a convolution operation of the forward shifted time reversal coefficient and the backward shifted time reversal coefficient, respectively, with a subsequently captured information sequence to obtain a forward shifted time reversal output and a backward shifted time reversal output; S4: processing the forward shifted time reversal output and the backward shifted 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.
