| 摘 要： | 在水下通信领域,由于物理场的限制,以声波作为载体的水声通信是解决水下远距离信息传输的唯一方法。水下声脉冲通信的发展对调制技术提出了更高的要求,脉冲位置调制（PPM）有较高的平功率利用率和传输速率,能够很好地满足实际需求。该设计介绍了脉冲位置调制的原理,详细阐述了脉冲位置调制解调设计方法并基于FPGA对PPM调制解调进行了设计,并用Quartus软件进行时序仿真,验证了设计的正确性。

| 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. |
