pca_new程序是一个用于降维的程序。用于降低数据的维数，更好精简冗余信息。(pca_new.m is used for data dimention reduction.)

质量导向算法是一种非常有效的相位解包裹算法，属于路径跟踪算法。质量导向算法的基本思想是用一幅质量图来引导相位展开，这个质量图可以用来描述包裹相位图中每个像素质量的好坏。(Quality oriented algorithm is a very effective phase unwrapping algorithm, which belongs to path tracking algorithm. The basic idea of the quality guided algorithm is to use a quality map to guide the phase unwrapping, which can be used to describe the quality of each pixel in the wrapped phase map.)

小波变换的程序包，具有多个程序，有很好的实频分析效果(Wavelet transform package, with a number of procedures, have a good effect of real-frequency analysis)

对MATLABB中给出的信号进行信噪比为4的WDEN小波去噪(The signal SNR the MATLABB given 4 WDEN wavelet denoising)

基于CP的最大似然估计仿真图，两幅图，分别是符号定时偏差，以及频偏，从图中可以看出在符号定时估计最大处，相应的频偏估计值也是最接近的(CP-based maximum likelihood estimate simulation map, two maps, are a symbol timing offset, and frequency offset, it can be seen the figure in the symbol timing estimation is maximum, the corresponding value is also the closest frequency estimation)
