Abstract An underwater acoustic channel blind equalization method via the blind source separation theory is presented. Constructing source signal by oversampling of the received signal, an on-line separation algorithm based on infoniax principle is employed to equalize the underwater acoustic channel. Convengence results in both time-invariant and time-variant, channel are studied. Simulation experiment shows that without the limit of minimum phase, the proposed algorithm gains promising results in multipath underwater acoustic channel.
