摘　　要：介绍了扩频通信技术,在MATLAB(Simulink)平台下建立了扩频通信的仿真模型,并对各个模块的功能进行了阐述。该仿真程序由序列发生器、直接扩频通信系统和正弦波干扰三个部分组成,模拟了直接扩频通信系统遭遇正弦信号干扰的情景,用蒙特卡洛仿真证明了直接扩频通信系统的良好抗干扰性能。This paper introduces a method of spread spectrum communication, and establishes a simulation model of direct spread spectrum communication on MATLAB （Simulink） and describes functions of each part of the model. Three parts, Gold sequence generator, direct spread spectrum communication system and sinusoidal signal interference are included in the Simulink system. These three parts simulate direct spread spectrum communication system in real life, using Monte Carlo simulation to imitate the situation when direct spread spectrum communi- cation system encounters sinusoidal interference and demonstrates its interference immunity.
