this program test certain system is timevariant or not. linear or not, causal or not

说明：  Floyd算法,求两点间最小路径,很有用(Floyd algorithm for the minimum path between two points, very useful)

co-ofdm的matlab仿真程序，包括文档代码解释和理论解释(coofdm matlab simulation program, including documentation of code interpretation and theoretical explanation)

求两个时间序列的相关系数，KL散度。可以比较时间序列之间的相关性(KL divergence && correlation coefficent)

FFT 快速傅里叶变换 matlab源代码(FFT)

這是一個利用butter filter 的bandstop 來濾除原始訊號中有雜訊的方法，先轉為spectrogram觀察雜訊所分步頻帶與能量，再依照要濾除的部分作bandstopa(This is a use of bandstop butter filter to filter out the noise of the original signal has a method, the first step into a spectrogram observation noise and energy of the band, then follow to filter out parts for bandstopa)

阵风风速模型，希望有人能用到，可以用作matlab风电场建模，双馈电机等方面(wind speed)

说明：  利用粒子滤波算法的对于非线性非高斯信号处理的优越性能，将之用于模态信号、振动信号去噪处理。(The particle filter algorithm for nonlinear non-Gaussian signal processing, superior performance, it is used for mode signal, vibration signal denoising.)

历届数学建模大赛的MATLAB的M文件，较为齐全。(Past mathematical modeling contest MATLAB M-files is complete.)

经典的数字信号处理书籍，Digital Signal Processing in Radar Image 里面有详细的SAR应用理论(an classic textbook related to Signal Processing and SAR application)
