摘　　要：利用Systemview软件作为平台,对扩频通信中最典型的扩频工作方式——直接序列扩频系统(DSSS)进行了仿真分析;结果表明直扩系统的抗干扰能力远远大于普通的二进制系统,并且随着扩频增益的增大,系统的误码率越小;同时扩频系统性能的好坏很大程度上还取决于扩频码的特性。In this paper, Systemview software as a platform for spread spectrmn communication of the most typical work of the KS-the system of direct sequence spread spectrum （DSKS） carried out a simulation analysis; the results showed that the DS system, anti-jamming capability is far greater than ordinary binary system, and with the increase of spreading gain, the smaller the bit error rate system; at the same time spread spectrum system performance is good or bad depends on a large extent, also the characteristics of spreading cedes.
