Learn-Matlab-7.0

这个与刚才的walawala3对比的程序。 是添加了高斯白噪声的。(this with just walawala3 contrast to the procedure. Is added to the Gaussian white noise.)

PCA的步骤： 1 先将数据中心化； 2 求得的协方差矩阵； 3 求出协方差矩阵的特征值与特征向量； 4 将特征值与特征向量进行排序； 5 根据要降维的维数d’,求得要降维的投影方向； 6 求出降维后的数据； (PCA steps: 1 of the first data center 2 covariance matrix obtained 3 obtained covariance matrix eigenvalues and eigenvectors 4 eigenvalues and eigenvectors will be sorted 5 according to the dimension of dimension reduction d ' , seek to reduce the dimension projection direction 6, the data obtained after the dimensionality reduction )

压缩感知可以用远低于奈奎斯特速率对信号进行采样，然后用重构算法对测量的信号进行重构，这程序就是CS的重构算法。(Compressed sensing can be used far less than the Nyquist sampling rate of the signal, and then use the measurement signal reconstruction algorithm to reconstruct this program is CS reconstruction algorithms.)

基于MVDR算法，计算两个信号的相关性的函数。(This program computes the coherence function between 2 signals x1 and x2 with the MVDR method. This algorithm is based on the paper by the same authors: J. Benesty, J. Chen, and Y. Huang, "A generalized MVDR spectrum," IEEE Signal Processing letters, vol. 12, pp. 827-830, Dec. 2005. x1, first signal vector of length n x2, second signal vector of length n L is the length of MVDR filter or window length K is the resolution (the higher K, the better the resolution))
