Abstract

A method of signal processing for underwater acoustic communication between N acoustic transmitters and at least one M remotely located acoustic signal receiver, comprises the following steps: configuring said transmitters and said receiver to share a common frequency band; ranking signals representing the power of at least two signal transmissions received by said receiver from said transmitters; employing N adaptive feedforward equalisers with a soft base band; whereby the method equalises Inter-Symbol Interference from multipath propagation and phase fluctuations; configuring a (N-I) adaptive feedforward equaliser to output a soft-decision to a N adaptive feedforward equaliser; and cancelling Multiple Access Interference generated from simultaneous asynchronous or synchronous reception of a plurality of signals.
