PCA Principal Component Analysismatlab代码(PCA Principal Component Analysis matlab code)

可见光室内通信中，接收端考虑散粒噪声和热噪声后的接收功率(Visible indoor communication, the receiving terminal receives the power to consider the shot noise and thermal noise after)

This toolbox contains functions related to image processing, including * images loading and generation. * filtering and blurring functions. * anisotropic and spacially variant filters. * non-linear filtering (median, LIC, bilateral). * High Dynamic Range image loading and equalization. * total variation image processing (denoising and decomposition). * non-wavelets image transforms such as local DCT

几个有关通信系统的matlab程序,有关信号，包含：a,对抽样频率为90kHz的信号进行下抽样抗混叠滤波器设计的程序，b,信号抽样率转换的程序，c,通过补零内插对信号进行下抽样，分析抽样对信号频谱的影响的程序(Some matlab programs about communiction system,mainly about signal,a,program about filter to signal sampling without aliasing ,b,transfering signal sampling rate,c,zeros-added sampling,with its influence of phase-frequency。)

用matlab实现巴特沃斯高通和低通滤波滤波，对图像进行相应的处理(Using matlab to achieve Butterworth high-pass and low-pass filtering filtering, the image corresponding treatment)

说明：  利用Matlab生成二维随机裂隙，控制裂隙密度、倾向、迹长分布函数、均值、标准差(Using MATLAB to generate two-dimensional stochastic fractures and control the density, tendency, trace length distribution function, mean and standard deviation of fractures)

This program makes it possible to generate a matrix of parity check LDPC with a constant weight of columns

说明：  Kernel pca基于核方法的特征提取算法(feature selection)
