Ricean Shadowed Statistical Characterization of Shallow Water Acoustic Channels for Wireless Communications
In this paper, the statistical behaviour of the shallow water acoustic channel for wireless communications is shown to be well characterized by the Ricean shadowed distribution, which has never been proposed for communication purposes on this type of channel. This characterization is clearly motivated from statistical and physical perspectives and has both theoretical and practical advantages compared to previously proposed models. Acoustic channel characterization is essential in modem design for underwater wireless communications. So far, there is not a general agreement about the most convenient channel model.
