摘　　要：System Vue是一个信号级的系统仿真软件,用户可以根据自己所需要研究的系统,构建仿真模型,设置修改系统参数,得到运行结果。本文利用System Vue这个仿真软件构造直接序列扩频通信系统的仿真模型,验证其系统的可行性。然后与普通二进制系统进行比较,得到两个系统对比的误码率图,结果表明直接序列扩频通信系统比普通二进制系统具有更强的抗干扰能力,最后通过改变扩频增益G的值来研究其对系统的影响。SystemVue is a system simulation software. Users can build simulation model, set parameters and get running results according to the system to be studied. In this paper, SystemVue is used to build simulation model of direct sequence spread spectrum communication system to verify its feasibility. And then it is compared with the common binary system, and the ber figure of the comparison of the two systems. The results showed that the anti-jamming capability of direct sequence spread spectrum communication system is far greater than that of the ordinary binary system. And finally the effect of the system is studied by changing the spreading gain of G value.
