电力线通信多径信道模型-Manfred Zimmermann模型，多径效应的传递函数H(f)可以用N条传输路径的叠加以及含有频率f、延时τ、距离d的方程来表示： H(f)=∑g_i *A(f,d_i )*e^(-j2πfτ_i ) 式中，i 为路径号， g_i为路径 i的加权系数(包含了传输系数和反射系数的作用)，A(f,d_i )为衰耗，其大小由长度、频率决定，τ_i是每条路径上的延时。 (Powerline Communication multipath channel model-Manfred Zimmermann model)

在原有matlab程序的基础上增加一个功能即原有程序在未统计之前，一个数默认频次为一，但是这个可以在频次不为1的情况下统计总的频次(Add a function on the basis of the original matlab program that is not before the original program statistics, a number of default frequency is one, but this can count the total frequency in the frequency is not a case)
