Title: Design of Underwater Acoustic Pulse Communication PPM System Based on FPGA
Abstract: In the field of underwater communication,as a result of the limitation of physical fields,underwater acoustic communication carried sound waves is the only way to solve information transmission over a long distance underwater.There is a high demand in modulation techniques due to the vigorous development of underwater acoustic pulse communication.Pulse position modulation(PPM)has higher average power utilization and transmission rate to meet the actual needs well.the principle of pulse position modulation is introduced,the PPM design method is expouded.PPM modulation system is designed based on FPGA,and the timming simulation for system in Quartus is made,the correctness of the design is verified.
