中文说明:
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。
English Description:
Manfred Zimmermann model is a multipath channel model of power line communication. The transfer function H (f) of multipath effect can be the superposition of N transmission paths, including frequency f and delay τ、 The distance D is expressed by the equation
