摘　　要：扩频通信技术是目前军事通信领域中的一种重要通信技术手段。本文主要介绍了直接序列扩频通信系统的基本原理及特点。并以SystemView仿真软件为平台,建立了Rummler干扰信道下的扩频通信系统,给出了详细的仿真模型和仿真结果,充分表明了扩频通信具有较强的抗干扰能力。同时又将衰落信道进行扩展,通过加入自定义干扰信道进行仿真比较分析,进一步证明了扩频通信很强的抗多径干扰能力。Spread Spectrum Communications is currently an important means of communication technology in the field of military communications. This paper describes the basic principle and characteristics of the direct sequence spread spectrum communications system, the Spread Spectrum Communications system over Rummier Channels is constructed on the Systemview platform, and the simulation model and simulation results are given in detail, it is indicated that Spread Spectrum Communications system has strong anti-jamming capability. At the same time, the fading channel is expanded into the custom channel, it is proved that the spread spectrum communication has strong anti-multipath interference ability by simulation and Comparative analysis.
