摘　　要：在MATLAB/SIMULINK平台上,采用相位搜索法设计并实现了扩频通信系统中PN码的同步仿真。对相位搜索法理论分析的基础上,利用Simulink通信系统仿真工具箱,建立了PN码同步系统仿真模型,分析了该系统的工作过程。仿真结果表明,利用Simulink仿真扩频通信中PN码同步系统,物理概念清晰,方法简单、实用。A MATLAB/Simulink based PN synchronization system simulation was designed and implemented by using phase acquisition method. Incorporated with the theory analysis of phase acquisition method, the model of PN synchronization system was built, and its working process was analyzed. The simulation results show that the method, that PN synchronization system was simulated by using Simulink, is easier and useful.
