随机信号：一段维纳滤波器的小程序，完成维纳滤波。(Random signal: Wiener filter for some small procedures, the completion of Wiener filtering.)

matlab中矢量控制模型，其中32变换可以用S函数来实现(matlab in vector control model, of which 32 can transform S function to realize)

展示GUI中如何在回调函数和其他函数中实现函数嵌套。(Demonstrate use of nested functions for callbacks and other functions.)

比较采用干扰消除和无干扰消除的V-BLAST系统误帧率与SNR的关系曲线。系统参数：收发天线个数M=4，N=6；设定发送信号总功率P=1；设定每一帧中的符号数Nframe=100；调制方式为16QAM；信道为不相关瑞利衰落信道。(Was used to compare the interference canceller and V-BLAST system without interference cancellation, the frame error rate and SNR curve. System parameters: the number of transmit and receive antennas M = 4, N = 6 set to send the signal power P = 1 set the number of symbols in each frame Nframe = 100 modulation for 16QAM channel is not related to Rayleigh fading channel.)

此程序能将一个信号进行EMD分解，已近调试过，绝对没问题，主程序为emd1.m，用户可以随意更改里面的信号函数Xn。(This program converts a signal with EMD nearly debugged, absolutely no problem, main program for emd1.m, the user can freely change inside the signal function Xn.)

由于PSO工具箱较难开发出多目标优化，采用MATLAB编写程序，得出VPPSO的源代码，进行优化设计，效果不错，希望和大家一起学习，共同进步(The PSO toolbox more difficult to develop a multi-objective optimization using MATLAB program, to draw VPPSO the source code, optimized design, good results, and we hope that with learning and common progress)
