中文说明：考虑雨衰 阴影 和多径影响，可以得到很精确的幅值、频率、相位估计，用于信号特征提取、信号消噪，matlab程序运行时导入数据文件作为输入参数，是学习PCA特征提取的很好的学习资料，可以广泛的应用于数据预测及数据分析。
English Description：
Considering the rain fading shadowing and multipath effect, the amplitude, frequency, phase of the very precise estimates can be obtained and used to signal feature extraction, signal denoising, matlab program is running into data files as input parameters is learning PCA feature extraction of very good learning materials, and can be widely applied to data forecasting and data analysis.
