可用于高光谱图像处理的自己编的PCA函数,Matlab版的.主要作用是降维.(the pca function is used to hyperspectral image processing.)

小波包变换可以对高频部分提供更精细的分解，而且这种分解既无冗余，也无疏漏，所以对包含大量中、高频信息的信号能够进行更好的时频局部化分析。(Wavelet packet transform can provide the high frequency part of the finer decomposition, and this decomposition is neither redundant nor oversight, so the signal contains a large amount of high frequency information can be a better time-frequency localization analysis.)

Modified Gram-Schmidt (MGS)正交化法是利用已有正交基计算新的正交基。既能选择相关特征，又能排出已选特征对后续特征选择的影响。(Modified Gram-Schmidt (MGS)orthogonalization gives new orthogonal basis through original orthogonal basis. It can do the feature selection and eliminate the impact on choosing new feature vector by the selected one.)

matlab系列教程2010年版，可有效学习matlab这一强大的工具(matlab tutorial series 2010 edition, which can effectively learn this powerful tool matlab)

说明：  文档中的matlab源代码主要是针对单回路液位控制系统的PID控制实现，内有simulink原理图(Matlab source code in the document is mainly for single-loop PID control of water level control system to achieve, within the simulink diagram)

平均误码率统计的的matlab程序，使用的时候还有一点注意事项，见程序内部说明(The average bit error rate statistics matlab program, when used, also Note, see the procedures for internal instructions)
