直接序列扩频通信系统的设计 摘 要：直接序列扩频通信系统（DS-CDMA）因其抗干扰性强、?隐蔽性好、易于实现码分多址（CDMA）、抗多径干扰、直扩通信速率高等众多优点，而被广泛应用于许多领域中。针对频通信广泛的应用，本文用MATLAB工具箱中的SIMULINK通信仿真模块和MATLAB函数对直接序列扩频通信系统进行了分析和仿真，使其更加形象和具体。 关键词：直接序列扩频通信系统，码分多址，MATLAB仿真，SINMULINK模块仿真 ABSTRACT：Direct sequence spread spectrum communication system because of its advantage such as strong anti-disturbance,hidden, being easy to realize CDMA ,anti-multi-path interference,DS communications rate higher strengths and so ,so it is widely used in many fields. With the wide use of the direct sequence spread spectrum communication technique , this text use communicatio
