| 摘 要： | 从理论上分析了多径效应和多普勒效应对无线信道的影响,并分别从时域和频域给出了信号经历信道后的仿真图形,分析了典型时变多径衰落信道理论模型,并在此基础上建立了抽头延迟线（TDL）的确定性仿真模型;仿真分析表明,通过改变时延功率谱和确定性模型的参数计算方法,此模型可以进一步扩展并用于多种传播环境下的小尺度衰落仿真。

| Abstract: | The influence of radio channel affected by multipath effect and Doppler effect is analyzed,and the transmitted signal simulation pictures of time domain and frequency domain are given.The deterministic time variant multipath fading channel is constructed by the tap-delay-line model,moreover,it can be extended to simulating kinds of small scale fading channels when the delay power spread and the method of parameters computation of deterministic simulation models are changed. |
