Underwater acoustic (UWA) communications allow wireless transmission between the surface and the bottom of a subsea environment based on acoustic waves. The wireless acoustic link reduces the physical infrastructure cost compared to the cable-based underwater communications. However, underwater acoustic channel imposes severe degradations on the transmitted signal. Its propagation characteristics are widely different from those of the radio channel. The multipath propagation caused by multiple reflections on the bottom and the surface, causes intersymbol interference (ISI) which must be compensated at the receiver. Furthermore, by the movement of the transmitting and receiving platforms, the UWA channel is time-variant yielding Doppler spre...
