| Zusammenfassung: | A underwater acoustic communication system between N acoustic transmitters and M remotely disposed acoustic signal receiver to form an underwater network comprises transmitters and receiver to share a common frequency band;ranking signals representing the power of at least two signal transmissions received by said receiver from said transmitter;observing a signal to determine if it has expanded or contracted within a predetermined time period;equalising Inter-Symbol Interference from multipath propagation and phase fluctuations; andcancelling Multiple Access Interference generated from receiving two or more signal transmissions. |
