Abstract :
Underwater acoustic communication network is one of the most challenging and complex researches in modern communication technology. In the paper, we proposed a method which could be used in point-to-point system as synchronization while as simple multi-access method in multi-point system. By using the time-frequency synchronization method as the prelusion of communication, the system could be suitable for the multi-point underwater acoustic communication application. Experiment showed that it could realize efficient detection in the weak signal conditions, and had high reliability and scalability.
