模极大值滤波，对信号进行分解和重构。所采用信号是matlab自带信号。(Modulus maxima filtering, the signal decomposition and reconstruction. Signal is used in signal matlab own.)

说明：  利用平稳随机信号各态历经性，用周期图法对随机信号进行功率谱估计(The use of smooth ergodic random signal, and use periodogram of random signals, power spectrum estimation)

this is the slides for WSN nodes

ETF统计套利的书籍，目前正在用matlab进行回测，希望有喜欢的人，也可以了解下(ETF statistical arbitrage books, is currently in use of matlab to test, hope to have of the person you like, also can understand)

MATLAB源程序，方便学习应用MATLAB(MATLAB source code to facilitate the application of MATLAB Study)

A radix-3 FFT for any N points. N is not limited to power of 3.

（1） 熟悉连续信号经理想采样前后的频谱变化关系，加深对时域采样定理的理解． （2） 熟悉时域离散系统的时域特性 （3） 利用卷积方法观察分析系统的时域特性． （4） 掌握序列傅立叶变换的计算机实现方法，利用序列的傅立叶变换对连续信号，离散信号及系统响应进行频域分析． ((1) familiar with the continuous signal to the manager before and after the sampling of the spectrum changes relations and deepen the time-domain sampling theorem understanding. (2) familiar with the time-domain system discrete time-domain (3) using deconvolution method of analysis in time domain characteristics. (4) master sequence Fourier Transform computer, using the Fourier transform sequence of continuous signals, Discrete signal system response and frequency domain analysis.)

matlab的二次拟合程序源码与大家分享！直接是M文件！(matlab secondary source fitting procedures to share with you! M file directly!)

用三种不同的方法（MS/MMSE/ML）估计cp同步的位置(Using three different methods (MS/MMSE/ML) estimate the location of sync cp)

matlab环境下的支持向量机源代码，支持支持向量机在小样本分析方面有很好的优势。(This is the source code of SVM in Matlab environment which is very ussful for analysis a small sample to support for classing.)
