中文说明：用clean算法提取信道的冲击响应 ，对于通信系统仿真很实用；包括一整套的仿真流程可以根据仿真目的对程序进行删减；后期数据处理比较有用
English Description：
Clean algorithm for extracting the impulse response of the channel, and is useful for communication system simulation; includes a full suite of simulation flow can make cuts to the program for simulation purposes; data processing more useful
