Surface Based Underwater Communications [PDF]
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010 In an underwater environment signal propagation for the acoustic channel is subject to major multipath effect. Therefore, most underwater communication schemes require that the position of the transmitter or receiver is fixed while using directional antennas in order to ensure high signal-to-noise ratio.
