摘　　要：介绍了时变信道对传输信号的影响以及时变信道的特点.通过分析时变信道的数学模型,根据时变信道自然形成的多径信号,以扩频通信为基础,利用Rake技术克服多径衰落,给出了仿真分析.The effect of time-varied channel on the transmitted signal and its characteristics are introduced in the article. Then the model of time-varied channel is analysed. According to naturally formed mulfipath by time-varied channel, the fading can be overcome through Rake technology based on spreading frequency communication. The simuhfions are given at the end of the paper.
