IEEE80211b_PHY_DBPSK

基于patch块的稀疏编码的matlab代码的实现，涉及到基和系数最小化的优化问题(Based on patch block sparse coding matlab code to achieve that relates to the base and the coefficient minimization optimization problem)

ask的调制（相乘法产生）、解调（想干解调）、误码率分析（已调信号添加高斯噪声再分析）(ask the modulation, demodulation, BER analysis)

Data Compression Huffman Coding Example Create an huffman alphabet for the input string Python 2.7 necessary (not tested Python 3.0). For windows just run huffman.bat

真正接触matlab一年左右，我很喜欢上了matlab的简单的语法,易于绘制图形,gui编 程也非常容易, 并且功能强大的开放式的toolbox。 因此,尽管我一直没有这方面的应用,但是我还是对 它非常感兴趣。 现 将个人的matlab的一点学习体会列在这里,愿能够对大家(特别是初学者)起到一点儿微薄 的作用也好。 (Real contact with matlab about a year, I am in love with the matlab syntax simple, easy to draw graphics, gui programming very easy, and powerful open toolbox. Therefore, even though I have not this application, but I still very interested in it. Matlab personal point now learning experience out here, we would like to be able to (especially beginners) to play the role of a little modest 也好.)

用matlab实现巴特沃斯高通和低通滤波滤波，对图像进行相应的处理(Using matlab to achieve Butterworth high-pass and low-pass filtering filtering, the image corresponding treatment)

非线性滤波的程序，里面包含扩展卡尔曼滤波和无迹卡尔曼滤波滤波，可应用于很多非线性系统(Nonlinear filtering process, which includes extended Kalman filter and unscented Kalman filter filtering can be applied to many nonlinear system)
