程序尚不完善，固定提取了3个主成分，没有做寻求最佳主成分个数；没有做交叉有效性检验 (good)

A linear method for data classification

本例程对十字形32QAM信号进行盲均衡处理，码间干扰可以降低到-30db，输出星座图更清晰(The routines of cross blind equalization 32QAM signal processing, inter-symbol interference can be reduced to-30db, output constellation diagram more clearly)

说明：  改进的HS算法,使用3*3加权平均模板，可以提高光流计算精度。(Improved HS arithmetic )

基于压缩感知的图像处理，分别使用二维DCT、FFT和一维dwt变换对图像信号进行稀疏变换，然后使用正交匹配追踪算法进行重构，在进行相应的逆变换(This is a image processing procedure based on compressed sensing which respectively uses two-dimensional DCT, FFT and one-dimensional dwt transform to sparse the image signal and then uses the orthogonal matching pursuit algorithm for reconstruction.)

LDPC码是通过校验矩阵定义的一类线性码，为使译码可行，在码长较长时需要校验矩阵满足“稀疏性”，即校验矩阵中1的密度比较低，也就是要求校验矩阵中1的个数远小于0的个数，并且码长越长，密度就要越低。 (LDPC Coding with PSK modulation in Rayleigh fading channel Most of the functions are built in matlab functions found in the comm. toolbox. These can also be easily configurable in the code to meet your requirements. In the given code, set the SNR, codeRate, modulation order (psk) and Number of frames to be simulated.

这是本人原创的数学建模论文，希望对参加数学建模建模的同学有帮助(This is the mathematical modeling of my original thesis, I hope to help students to participate in the mathematical modeling modeling)

这是胡不变矩的经典matlab程序，其实就是不变矩的验证，七阶矩.(This is the classic Hu invariant moments matlab program, in fact, the same moment the validation, seven-order moments.)

空时自适应处理是阵列天线杂波抑制的一种有效方法，该代码是空时级联自适应处理的一种实现方式，供大家参考(Space-time adaptive processing is array antenna is an effective method of clutter suppression, the code is the space-time cascade an implementation of adaptive processing method, for everybody reference )
