中文说明：通信中用的clean算法提取信道冲击响应的代码TH-PPM信号产生和接收仿真（AGWN信道）通过UWVB四个信道，并且对互相关峰值设定了门限0.001，重新设置了起始时间可以根据自己的数据情况修改门限和起始时间CLEAN算法的原理如下：应用CLEAN算法首先要获得模板信号，然后应用相应的迭代算法，利用模板信号从接收信去除影响，从而计算出信道的冲激响应。
English Description：
Clean algorithm used in communication channel impulse response simulation of TH-PPM signals and receive the code (AGWN channel) by UWVB four-channel, And cross-correlation peak set a threshold of 0.001, reset start time according to their own data, modify the threshold and the start time of CLEAN algorithm is as follows: CLEAN algorithm is applied first of all to get the template, and then apply the corresponding iterative algorithm, using template removal effect signal from the receiver, then worked out the channel impulse response.
