说明：  通过一个循环方阵A来构造准循环LDPC码的校验矩阵H(make H in QC-ldpc)

关于主元分析选取方法重构误差方差法（VRE）的MATLAB仿真代码。(About PCA reconstruction error variance method selection method (VRE) MATLAB simulation code.)

PorousMedium2LayerModel双向介质波长模拟(Porous Medium 2Layer Model)

一款工作于2.4 GHz 频段的带有源负载的高性能双平衡有源混频器0479-8023(2012)04-0538-07(A High Performance Double-Balanced Gilbert Mixer with Active Loads for 2.4-GHz ISM Band Application)

removing noise from ecg signal

对pam调制的误码率进行理论和仿真对比，用的是蒙特卡罗方法(01:15 modulation of the BER and the theoretical simulations, using the Monte Carlo method)

一些通信仿真实例,是我自己一直在用的东西，查了好久的，希望有用(Some test,helpful)

使用样本协方差矩阵求逆方法仿真的波束图。使用的是均匀线列阵，信号方向为10度，有噪声，没有干扰。(Using the sample covariance matrix inversion method for the simulation beam pattern. Using a uniform linear array, the signal direction of 10 degrees, there is noise, no interference.)

本书基于MATLAB的图像处理工具箱,全面系统介绍了图象处理工具箱在图形绘制,图像几何变换,图像增强,小波分析和分形几何用于图像处理,以及图形用户界面设计等在工程中的实际应用.(book based on MATLAB Image Processing Toolbox. a comprehensive system of image processing toolbox in graphics rendering, image geometry transform, image enhancement, Wavelet analysis and fractal geometry for image processing, and graphical user interface design project in the practical application.)

汇集了大量的小波分析例子，详细的介绍小波分析的应用范围(Collection of a large number of examples of wavelet analysis, detail the scope of application of wavelet analysis)
