数字通信程序。记录我针对数字通信（John.G Proakis）版本学习中编写的仿真程序。 和大家交流共同学习，其中的错误，希望大家指证！ (Digital communication procedures. I look at digital communications records (John.G Proakis) version of the study prepared by simulation program. And to facilitate the exchange of learning, in which the error, hope that means the card!)

ROC曲线~在信号检测理论中,接收者操作特征(receiver operating characteristic),或者叫ROC曲线是一种对于灵敏度进行描述的功能图像.ROC曲线可以通过描述真阳性率(TPR)和假阳性率(FPR)来实现.由于是通过比较两个操作特征(TPR和FPR)作为标准,ROC曲线也叫做相关操作特征曲线(ROC curve ~ in signal detection theory, the receiver operating characteristics (receiver operating characteristic), or called the ROC curve is a function that describes the sensitivity of the image. ROC curve can describe the true positive rate (TPR) and false positive rate ( FPR) to achieve. because it is by comparing the two operating characteristics (TPR and FPR) as a standard, ROC curve is also called the relevant operating characteristic curve)

能够进行各向异性的差分等效介质（Differential Effective Medium Model）理论，获得各向异性介质的弹性张量(This programme could be used to build anisotropic elastic model by anisotropic Differential Effective Medium Model)

说明：  这个仿真程序可以仿真牛头刨床的运动形式，解牛头刨床的运动加速度等。(This simulation program can simulate the form of the movement of the planer, the solution of the movement of the planer acceleration.)

通信系统仿真原理与无线应用第三章全部程序(Communication System Simulation Principle and wireless applications of all procedures in Chapter III)

说明：  一个关于QAM调制的MATLAB仿真程序， 只有源码，已经调试过(A QAM modulation on MATLAB simulation program, only the source, has been debugged)

基于MATLAB的几种数字调制仿真，包括2ASK、4ASK，2PSK，4PSK，QAM等调制方式。结合GUI图形表示出来。内含两个文件，一个是digital_modulation.fig图形文件，另一个是digital_modulation.m源码文件。(digital_modulation)

MLPG is a combination of collocation method and EFG

一个较好的无刷直流电动的MATLAB的仿真模块，有图有真相，祝各位好运。(A better brushless DC electric MATLAB simulation module, there are pictures and the truth, and I wish you good luck.)
