中文说明：输入信号为2PPM-TH信号，经过UWB信道后得到接收信号，通过这一过程，进而得到信道的冲击响应，画图显示冲击响应，由UWB信道的冲击响应图可知，UWB信号能量主要集中在前几路信道上，由于信道衰减，时延长的路径上的信号到达接收端以后几乎为零。。。
English Description：
The input signal is 2PPM-TH signal, after UWB channel to get the received signal, through this process, and then get the impact response of the channel, drawing show the impulse response, by the impact of UWB channel response figure shows, UWB signal energy is focused on the first few path channel, since the channel attenuation, the signal path when extended reach almost zero after the receiving end. . .
