说明：  MATLAB小波分析___张德丰——源代码，对于学习小波分析很有帮助。(MATLAB Wavelet Analysis)

本程序重构各层低频和高频系数，画功率谱，横坐标为频率，纵坐标为功率，小波包分解最后一句是为显示小波包四层分解树结构(Reconstruction of the procedural layers of low and high frequency coefficients, draw power spectrum, the abscissa is the frequency, the vertical axis is power, wavelet packet decomposition is the last sentence of four to show the wavelet packet decomposition tree)

图像的颜色特征提取，通过选择合适的阈值，将对象从复杂背景中提取出来(Image color feature extraction, by selecting the appropriate threshold, the object is extracted from complex background)

决策树算法的matlab实现，主要适用的是id3 算法思想(Decision Tree Algorithm to achieve the matlab main id3 algorithm is applicable to thinking)

Matlab的OFDM在多径Rayleigh信道下的同步 1. 假设频率已同步，设计OFDM一种具体的采用循环前缀进行时间同步方法，用Simulink进行仿真，画出比特信噪比与捕获概率的关系曲线。 2. 设时间已同步，设计OFDM一种具体的采用循环前缀进行频率同步方法，用Simulink进行仿真，画出比特信噪比与频率同步误差的关系曲线.(Matlab-OFDM in multipath Rayleigh channel synchronization 1. Assume that the frequency has been synchronized, the design of a specific OFDM cyclic prefix for time synchronization method, using Simulink simulation to depict the bit signal to noise ratio and the capture probability curve. 2. Set up time is synchronized to design a specific OFDM cyclic prefix for frequency synchronization method, using Simulink simulation to depict the bit signal to noise ratio and frequency synchronization error of the curve.)
