自适应的粒子群优化算法，作毕业设计的同学可以看看(Adaptive Particle Swarm Optimization for graduate design students can see)

此程序由matlab实现,用于对语音信号的功率谱密度进行估计.希望能有所帮助.(this procedure from Matlab realized, for the speech signal power spectral density estimation. hope to be helpful.)

Ofdm simulation with equalization

好用地 matlab 区域增长算法，先输入比较范围，再输入种子点数目，然后就是手动选取种子点了 ，好运哦！(good land Matlab regional growth algorithm, importing more scope to import seed spots, Then, they manually select seed, good luck!)

a useful matlab code

ELMAN神经网络的系统分类算法，修改可用，运行环境为Matlab。(System classification algorithm, ELMAN neural network to modify the available, operating environment for the Matlab.)

用于绘制滚动轴承故障的频谱图和包络解谱图，从而判断轴承故障(Used to draw the rolling bearing fault frequency spectrum and spectral envelope solutions, in order to determine bearing failure)

说明：  扩频水印技术的MATLAB程序(Spread Spectrum Watermarking MATLAB)

说明：  卡尔曼滤波器matlab源码，初学者可以作为参考，也可以直接应用(Kalman filter matlab source)

永磁同步电机的一个仿真模型，使用了电流和转速双闭环控制。(Permanent magnet synchronous motor, a simulation model, using the two-loop current and speed control.)
