用MATLAB中的simulink对DQPSK进行仿真(Using MATLAB in the simulink simulation of the DQPSK)

foptions.m, filtering for matlab

实现hilbert变换，经过与matlab比较验证，结果相同(Achieve hilbert transform, through comparison with matlab verification, the same result)

routine to take the Fourier transform of a signal and plot both the time and frequency domain representations. Typical use: >> n = 100 number of data points >> dt = 0.01 spacing between samples >> t = 0:dt:(n-1)*dt time vector >> y = sin(2*pi*10*t) 10 Hz sin wave >> fft_plot(y,dt) plot of signal in time and frequency domain

this source code is very good

S变换的逆变换源程序，用于matlab环境下。.t的格式(The S transform inverse transform source code for the Matlab environment. Format. T)

视频水印，在每一帧视频帧上嵌入水印，不可见性良好(video waterMarking,embed the watermark on each frame of video,invisibility is mediocre)

基于双端电气量的故障测距，里面的输电线路是分布式输电线路，所以该模型已经考虑到了分布参数对测距的影响，能进行稳定而精确的测距！(Based on samples at both ends of the fault location, inside the transmission line is a distributed transmission line, so that the model has taken into account the effect of the distribution parameters ranging, enabling stable and accurate distance!)

本程序是在MATLAB中对LMS均衡算法的通信仿真。(This procedure is in the MATLAB algorithm of LMS balanced communication simulation.)

分割算法 1.mean shift 的迭代过程只做了一次（为了简单） 2.对图像中的某一点进行平移时，只考虑了距离它小于2*hr的点，而不是图像中所有的 点。 3.实验过程中只用到了gauss核，虽然提供了method的选择，但在进行值域加权时只用 到gauss核，如果需要请自己改正。(mean shift algorithm )
