摘　　要：以扩频理论为基础,利用Matlab的可视化工具Simulink建立了直接序列扩频通信系统的仿真模型,详细阐述了模型各个模块的设计。在给定的仿真条件下,对仿真模型进行了运行测试,结果符合预期效果。同时利用仿真模型研究了直扩通信系统扩频增益、干扰容限与误码率及信道信噪比之间关系,为其抗干扰的实际应用奠定了基础。Based on the spread spectrum theory, the simulation model of the direct sequence spread spectrum（DSSS） communication system is built by using Simulink which is a visible tool of Matlab in this paper, each module design of simulation model is introduced in detail. Under the given simu- lation condition, the simulation module is run and detected, the result answers for the anticipated effect. Meantime, this paper studies the relationship among the spread spectrum gain and interference tolerance of DSSS communication system, error ratio, SNR of channel by means of the simulation module,which establishes the base for the practical application of its anti-jamming.
