里面包含m序列，gold序列的生成函数，还有自己编写的自相关函数的M文件。(Which contains m-sequence, the gold generating function of the sequence, as well as I have written the autocorrelation function M-file.)

代码里有很完整的注释和解释，是学习PCA特征提取的很好的学习资料，在MATLAB中求图像纹理特征，关于神经网络控制，添加噪声处理，抑制载波型差分相位调制。

非线性降维方法lpp 可以应用于高维数据的机器学习(Lpp nonlinear dimensionality reduction methods can be applied to high-dimensional data, machine learning)

QR Decomposition for non quadratic system

主要是些matlab的常用指令，对大家可能会有所帮助(Mainly those commonly used matlab instructions may help to everyone)

The extraction of high-resolution ECG signals from recordings contaminated with back ground noise is an important issue to investigate. The goal for ECG signal enhancement is to separate the valid signal components from the undesired artifacts, so as to present an ECG that facilitates

mvdr,程序，希望对大家学习水声中的波束形成有用啊(mvdr, procedures, we hope to learn the acoustic beam forming useful ah)

MATLAB教程，中附有很多源代码，希望对下载的人有所帮助(MATLAB Guide, with a lot of source code, and I hope to the people who download help)

说明：  自编灰色预测MATLAB程序，可供初学者使用(The grey prediction matlab program is compiled by ourselves, which can be used by beginners)

说明：  利用通信系统中调制信号的循环平稳特性,对频谱空洞进行检测,提升频谱感知技术在低信噪比下的性能。实验结果表明:与传统能量检测方法相比,采用循环特征检测方法改善了认知无线电中频谱空洞的检测能力。(Based on the cyclostationarity of modulation signals, spectrum hole is detected, aiming at the improve- ment of the performance of spectrum sensing in low SNR situation. The results show that comparing with the tra- ditional energy detection technique, cyclostationarity-based spectrum sensing technique has greatly improved the detective ability in cognitive radio.)
