Abstract

The Ocean is a dynamic and complex environment; it is a very complicated transmission channel that can change rapidly with the environmental conditions. Hence, to avoid failure of underwater monitoring missions, it's crucial to predict the behavior of underwater acoustic channel. In this paper, several fundamental key aspects of underwater acoustic channel are investigated. A model characterizing the underwater acoustic channel is introduced, and how underwater channel can be simulated is discussed. In addition, this paper describes a methodology for top-down design, modeling, and simulation of underwater channel using hardware description language VHDL-AMS. The following analysis may provide precious guidelines for the design of underwater communication systems.
