Wiener filter based on tracking a priori SNR usingDecision-Directed method, proposed by Scalart et al 96.(Wiener filter based on tracking a priori SNR usingDecision-Directed method, proposed by Scalart et al 96.)

这本书不错，适合滤波器的学习用，程序已经调试通过。(This book is good for learning to use filters, testing procedures have been adopted.)

说明：  根据输入数据，用RBF网络实现模型建立！欢迎交流！(According to the input data, using RBF network model! Welcome to exchange!)

创建动画 播放动画 分别读入图像 用imshow函数显示(Play the animation to create animated images were read into the display with the imshow function)

double pendulum simulation in matlab

用于齿轮信号的倒频谱分析，程序是通的，只需修改数据文件就可以。(Cepstrum analysis for gear signal,it is through,only the data files can be modified.)

说明：  采用改进的蚁群智能算法，得到车辆最短路径问题快速有效的局部最优解。(The improved ACO to obtain the shortest path problem vehicle fast and effective local optima.)

说明：  本程序运行需一个小时左右。优化准则是旁瓣电平最小。取栅格间距为lemda/2,阵元间距为栅格间距的整数倍。放阵元的位置放1，否则放0(This program should be running an hour or so. Rule of optimization is side-lobe level minimum. Take grid spacing for lemda/2, spacing for grid spacing array (integer times. Put the position of the array (put 1, otherwise put 0 )

We see that HTH matrix is almost diagonal as the off diagonal elements are nearly zero. So we are getting exact estimation in case of PRN INPUT due to diagonality of HTH matrix. As seen that the unknown inpulse response ( h ) and estimated impulse response ( hth ) are coming out to be exactly same. The estimation even gets better for large N .as we get the HTH matrix perfect diagonal. So we come to know that we can estimate the unknown parameters exactly when PRN input is used.

The function impulsive_noise generates non-gaussian noise with inputs of beta, gamma,and the power of noise is 1 in W or 0 in dB. The noise can be defined either real or complex. The other functions generate QAM symbol and insert a vector to another vetor with specific locations
