摘　　要：扩频通信在频谱利用率、通信保密性、通信抗干扰等方面都有着突出的表现,将扩频通信理论与软件无线电思想相结合是当今通信领域中新兴的研究方向.介绍扩频通信系统平台设计,提出m序列的软件产生思想,给出多DSP网络产生伪随机码的实现方法,并给出具体实现的部分源程序,具有一定的实用价值.文章分析了该系统的硬件构成,阐述了系统工作原理,并给出部分软件和程序流程图.The technology of spread spectrum communication has excellent performance at the spectrum efficiency,secure communication and anti-jamming communication. The combination of the spread spectrum communication theory and SDR has been an emerging research direction in communication domain in nowadays. This article introduces the platform design of the spread spectrum communication system,proposes a kind of idea about generating software of m-sequence,and gives the method which can generate pseudo-random code by multi-DSP network and attaches some source code,which has certain practical value. And in this article the hardwares in this system are analyzed,work principium is introduced and partial software and procedure chart have been given.
