Digital communications have been traditionally treated using signal processing approaches. Algorithm and performance is system-model dependent. For underwater acoustic communications, the system model is very complex due to the different channel environmental conditions which can vary rapidly with time, and are location dependent. Performance modeling is difficult without a profound channel model. Work over the last decades have shown that robust performance can be achieved by exploiting the channel physics allowing at the same time an initial estimation of the communication performance. This paper will review the basic signal processing approaches using languages familiar to the physicists/acousticians, point out the communication related physics issues, and discuss how channel physics can be exploited to improve the performance.
