Root-MUSIC-MATLAB

对图像进行JPEG压缩编码和解码，用matlab实现(JPEG compression of image encoding and decoding, using matlab implementation)

ceemdan，改进的eemd程序,里面有ceemdan的程序，也有心电数据，和一个应用程序。(Ceemdan, an improved EEMD program)

用matlab来仿真ofdm调制算法，ofdm技术用于4G无线通信系统。(Ofdm simulation using matlab to modulation algorithm, ofdm technology for 4G wireless communications systems.)

matlab 入门基础知识，数字图像处理系列入门教材系列之一(Basic knowledge of introduction to matlab, digital image processing one of series of introductory textbook series)

最速梯度法工具箱，添加方法在命令窗口中敲入pathtool，会出现一个setpath的窗口，点add folder或者add with subfolders按钮，选中你的工具箱。保存既可。任选工具箱中的一个命令，然后help一下看看是否好使。(Toolbox steepest gradient method, add the method in the command window and typing pathtool, a setpath window appears, point add folder or add with subfolders button, select your toolbox. Save both. Choose a command in the toolbox, and then help look to see if so.)

经典的MUSIC算法可对非相干信号实现很好地估计，在相干信源的情况下经典的MUSIC算法失效，无法准确估计出信源波达方位角度。引入空间平滑技术来对相干信号进行预处理,以减弱或消除信号之间的相干性，改进后的MUSIC算法能对相干信号的DOA 实现精确估计。(The classical MUSIC algorithm can achieve a good non-coherent signal is estimated that in the case of coherent sources the classic MUSIC algorithm is disabled, can not accurately estimate the source azimuth angle of arrival. Spatial smoothing technique to the introduction of coherent signals pretreatment to weaken or eliminate the coherence between the signals, the modified MUSIC algorithm for DOA of coherent signals to achieve precise estimates.)

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 AVL tree program that keeps the balance of the tree while deleting numbers

Simulation of digital baseband modulation,it is very good for the users to deepen their understanding
