摘　　要：本文基于SystemView系统仿真平台,设计了差分相移键控(DifferentialPhaseShiftKeying,DPSK)通信系统的仿真模型。其调制部分采用了差分编码模块,得到差分码,进行绝对调相产生DPSK信号;并且解调部分采用差分相干解调法还原出伪随机序列。仿真结果表明,利用SystemView软件仿真,可以有效地得到所设计电路的输出结果,体现了SystemView进行系统仿真的可行性与实用性。Based on Systemview system simulation platform,this paper designs the simulation model of differential phase shift keying(DPSK)communication system.The modulation part adopts the differential coding module to obtain the differential code,perform absolute phase modulation and generate DPSK signal;In the demodulation part,the pseudo-random sequence is restored by differential coherent demodulation.The simulation results show that the output results of the designed circuit can be effectively obtained by using Systemview software simulation,which reflects the feasibility and practicability of Systemview system simulation.
