Abstract
In the past decade, the research of underwater acoustic communication is focus on shallow water. Due to the land resources like petroleum are going to exhaust, improves the techniques of underwater acoustic communication are in an urgent need. For underwater communication, the most important problem is that the ocean environment is a time-varing system. That means the underwater channel changing by different time. In this paper, we use some channel analysis to understand the characteristics of shallow water channel, the most important thing is discussing the relationship between coherent time and phase rate. Phase coherent communications provide a high data rate transmission in a band-limited underwater acoustic channel. Therefore, it is important to know about the coherent time and phase rate.
