初步能改变难度的代码，希望对大家有效。相互学习一下(The initial difficulty of the code change and hope to everyone effectively. Learn from each other about)

说明：  信号处理输入相关矩阵的创建程序以及傅里叶变换(Signal processing procedures for the creation of the input correlation matrix and Fourier transform)

小波去噪的阈值去噪发法，在图像方面很有用(Wavelet denoising threshold denoising hair method is useful in image areas)

阵列信号处理中MUSIC算法估计DOA,MUSIC算法是一种基于矩阵特征空间分解的方法。从几何角度讲，信号处理的观测空间可以分解为信号子空间和噪声子空间，显然这两个空间是正交的。(Array signal processing MUSIC algorithm for DOA estimation,MUSIC algorithm is a method of feature space based on matrix decomposition. From the geometric point of view, can be observed spatial signal processing decomposition into the signal and noise subspaces, obviously these two spaces is orthogonal.)

ofdm system for wireless communication both transmitter and receiver part for AWGN channel.

利用PSO算法优化SVM向量机参数。测试指标为MAPE和均方根误差。(Optimization of SVM Parameters by PSO Algorithm. The test indexes are MAPE and root mean square error.)

双基（机载）合成孔径雷达测高——比较没技术含量，因为用的方法是斜距差，没用相位差（还没研究出来），所以误差有点大。(Double-base (Airborne) synthetic aperture radar altimeter- not the technical content of comparison, because the methodology used is inclined away from the poor, no phase difference (not finding out), so a bit big error.)
