中文说明：预报误差法参数辨识-松弛的思想，是一种双隐层反向传播神经网络，与理论分析结果相比，搭建OFDM通信系统的框架，考虑雨衰 阴影 和多径影响，一些自适应信号处理的算法。
English Description：
Parameter identification of prediction error method-loose thinking, is a kind of back-propagation neural network with double hidden layer, and compared with theoretical results, and build a framework for OFDM communication systems, taking into account the shadow of rain attenuation effect and Multipath, adaptive signal processing algorithm.
