利用两步法辨识Hammerstein模型，用到了特殊的输入信号，已经上传。(ication of Hammerstein Model using two-step method, to use a special input signal has been uploaded.)

evolutionary optimization in matlab code

对图像进行多级小波分解、重构。可用于提取图像的背景噪声(Multi-level image wavelet decomposition and reconstruction. Can be used to extract image background noise)

说明：  这是一种BP神经网络的的MATLAB的代码有用请下载(if it help,please go ahead)

Implementation of the Non local filter for image denoising

说明：  用于模拟时变非平稳的ARMA过程，根据Doppler频移和时变参数计算ARMA过程的系数，可以用来模拟非平稳的多径衰落信道(used to simulate nonstationary time-varying ARMA process, according to Doppler frequency shift and the time-varying parameters ARMA process coefficient, can be used to simulate the non-stationary over Fading Channels)

语音基音频率的检测方法matlab编程 自相关法和同态滤波法(Pitch detection methods matlab programming frequency autocorrelation and homomorphic filtering)

OVERLAP ADD METHOD FOR CALCULATING THE CONVOLUTION OF LONG SEQUENCE

说明：  这是一个基于matlab的BP算法程序，采用标准的BP算法，通过修改各层节点数即可实现函数优化。 (This is a matlab-based algorithm of the BP procedure, standard BP algorithm, by modifying the number of nodes can be realized at all levels function optimization.)
