The power line channel noise is simulated by MATLAB and the attenuation is simulated through the channel transmission module of FIR filter.
利用MATLAB及用fir滤波器做信道的传输函数模型对信道噪声和复衰减特性分别进行了建模。
But, there exists serious noise and channel attenuation in power line and they affect the quality of communication seriously.
但由于电力线路存在着强噪音、信道衰减等原因，严重影响了通信质量。
Secondly, power line noise channel and multi-path channel optimization modeling techniques based on artificial neural network are proposed.
其次，提出了电力线噪声信道和多径信道的神经网络优化建模方法。
