Abstract :
As the underwater acoustic channel is time-frequency variable, the synchronization plays an important role in whole communication. In this paper, the tradition signal of LFM (linear frequency modulation) is taken as the synchronization signal, and a flexible technique method to detect LFM signal are proposed with little resources. Compared to the basic one, the optimized structure uses the multiple-cycle technology to finish computation. Also the detail design and implement results with FPGA (Field Programmable Gate Array) will be given, and it is verified by simulation and field data that the method is feasible.
