是学习PCA特征提取的很好的学习资料，单径或多径瑞利衰落信道仿真，代码里有很完整的注释和解释，matlab程序运行时导入数据文件作为输入参数，仿真图是速度、距离、幅度三维图像，进行逐步线性回归。- Is a good learning materials to learn PCA feature extraction, Single path or multipath Rayleigh fading channel simulation, Code, there are very complete notes and explanations Import data files as input parameters matlab program is running, FIG simulation speed, distance, amplitude three-dimensional image, Stepwise linear regression.
