说明：  时频分析工具箱，还有说明和源程序。很好的东西(Time-frequency analysis toolbox, as well as notes and source code)

CDMA多用户检测的Simulink仿真研究(CDMA multi-user detection of Simulink Simulation)

This example shows the use of the FFT function for spectral analysis. A common use of FFT s is to find the frequency components of a signal buried in a noisy time domain signal.

Algorithm that find the peaks of a signal. You can choose the number of peaks you want to find and the valour of peak to begin to find.

说明：  这个程序是m序列发生器,它能产生M序列 程序简明扼要 容易运行(This procedure is m sequence generator, it can produce concise and easy to process M running sequence)

凸包 凸包问题的实现 有无数点，求能包含这些点的图形的最小面积(Convex hull Convex hull problem of realization there are numerous points, seek to include these points, the graphics, the minimum size)

说明：  基于多卫星的GPS中频信号生成方法，通过分析单卫星信号的模拟搭建，改进为多卫星的实现方法。(Based on the multi-satellite s GPS intermediate frequency signal production method, through analyzes the single satellite signal the simulation build, improves realizes the method for the multi-satellites.)

基于MRAS无速度传感器的永磁同步电机的仿真模型，可以实现较好的仿真结果。(MRAS based speed sensorless permanent magnet synchronous motor simulation model, can achieve a better simulation results.)

用matlab画出smith圆图的M文件，已经验证，结果正确，部分行需要去掉回车即可运行。(Draw smith chart matlab M-file has been verified, the result is correct, part of the line needs to be removed then press enter to run.)

DCT 3D function for signal
