GPS卫星定位 利用伪距观测量计算用户位置(GPS satellite positioning using pseudo-range observables calculated user location)

说明：  matlab里面使用三倍中误差法消除观测粗差，去除噪声。(matlab error method which uses three times in the elimination of Gross Errors, remove noise.)

《matlab通信工程仿真》源码，张德丰主编，机械工业出版社。里面的readme文件介绍了本书的目录和版本。(" Matlab Communication Engineering Simulation" source, Zhang Defeng editor, Machinery Industry Press. Inside the readme file describes the directory and the version of the book.)

This is amatlab code fo compression with psychoacoustique

此代码只要是自然梯度算法（naturalness_gradident_arithmetic，使用matlab编写的，一起学习(This code as long as it is the natural gradient algorithm (naturalness_gradident_arithmetic, using matlab prepared to learn)

4万亿投资的数模论文与实现的源代码，自己在学习数模课程的作业(4 trillion investment in digital to analog Papers and the source code, in the course of the digital-analog operations)

关于SVM toolbox的详细使用说明，使读者可以很快的会使用SVM matlab工具箱(About SVM toolbox for details on these, so that readers can quickly use the SVM matlab toolbox)

dw检验Matlab源码，傻瓜型，检测值矩阵已经在程序中准备好了，无需查询。直接导入数据出结果。解压后为m文件(dw test, easyused，import the data directly to the results. detection value matrix have been ready in the program, without having to query.)

关于导航定位中的卡尔曼滤波程序。X1，X2分别代表经过转换以后的位置X,Y轴的坐标。V1，V2为其相对应的速度。卡尔曼滤波可以使定位数据更加平滑。(Calman filtering program in navigation and positioning. X1, X2, respectively, after conversion to the position of the X, Y axis coordinates. V2, V1 for its relative speed. Calman filter can make the positioning data more smooth.)

旨在仿真OOK信号，这是国家重大项目的一个子课题，编译程序验证(Designed to simulate OOK signals, which is a sub task of national major projects, compiler verification)
