无线信道时延扩展仿真 一、仿真目的 　　　在数字通信中，无线信道所表现出的时延扩展将有可能引起接收信号的码间串扰。实验的目的是从时域角度方面对移动信道的多径环境引起的接收信号时延扩展现象进行仿真。(wireless channel delay spread simulation One, the simulation purpose In digital communication, wireless channel delay spread shown will likely cause the received signal crosstalk code. The aim of the experiment is to delay the received signal due to multipath environment of mobile channel in time domain and the phenomenon of simulation.)
