中文说明：一些自适应信号处理的算法，有信道编码，调制，信道估计等，有较好的参考价值，用于信号特征提取、信号消噪，真的是一个好程序，是学习PCA特征提取的很好的学习资料。
English Description：
Algorithm of adaptive signal processing, channel coding, modulation, channel estimation, and so on, have a good reference value, used for signal feature extraction and denoising, is really a good program, PCA is learning good study material feature extraction.
