BP算法程序，通过此程序可以很好的对两类模式进行分离。效果明显。(BP algorithm program can be very good through this process to separate two kinds of models. Effect is obvious.)

说明：  在灰度范围[100,200]内显示图像，以灰度等级20显示图像(In gray-scale range of [100,200] display image to 20 gray levels display images)

设计一个一维wiener滤波器，并以平稳信号加噪为输入，得到该平稳信号的估计信号，并求出最小均方误差。(Design a one-dimensional wiener filter, and to smooth the input signal plus noise to get the estimated signal of the stationary signal, and find the minimum mean square error.)

有关通信系统中信道同步的问题，希望与大家切磋，多多指教。(the Channel Communication System synchronization issues, and we hope that the discussions and exhibitions.)

设计一个信号发生器,并同时画出信号的时域表 示，自相关函数及功率谱(Design of a signal generator and simultaneously draw the time domain representation of the signal, the autocorrelation function and the power spectrum)

MATLAB仿真程序，基于直流输电系统（HVDC）的MMC（modular multilevel converter）结构变流系统。程序主要包括主变流部分及其控制部分，MMC为7电平结构。程序测试OK。(a power convertion system realized in MATLAB SIMULINK. the system is carried out with a kind of newly investigated converter named Modular Multilevel Converter of seven levels.)
