通信原理实验的matlab仿真中的快衰落和慢衰落(Matlab simulation experiment of communication principle in fast fading and slow fading)

说明：  关于解线性方程组的直接法的常见matlab程序。可直接使用 (解线性方程组的直接法)

经典的功率谱和 双谱估计，很好，看看能用上的。(Classic power spectrum and dual spectrum estimation, well, look at can be used on.)

基于压电传感器的振动测试探头的matlab模型(Based on piezoelectric vibration sensor test probe matlab model)

OMP算法的本质思想是：以贪婪迭代的方法选择D的列，使得在每次迭代的过程中所选择的列与当前冗余向量最大程度的相关，从原始信号向量中减去相关部分并反复迭代，只到迭代次数达到稀疏度K，停止迭代。(OMP compressed sensing )

基于混合高斯模型的matlab代码，用于求概率问题，可行，已经运行过了(Based on Gaussian mixture model matlab code for the required probability problems, feasible and has been running over)

严格按照BP网络计算公式来设计的一个matlab程序,对BP网络进行了优化设计 优化1：设计了yyy，即在o(k)计算公式时，当网络进入平坦区时(<0.0001)学习率加大， 出来后学习率又还原 优化2：v(i,j)=v(i,j)+deltv(i,j)+a*dv(i,j) (A Matlab procedures in strict accordance with the BP network computing formula to design, the optimization design was carried out on BP network Optimization design of 1: YYY, that is O (k) in the formula, when the network into the flat area (<0.0001) learning rate increase, after learning rate and reduction Optimization of 2:v (I, J) =v (I, J)+deltv (I, J)+a*dv (I, J) )

HHT谱计算程序，不是rilling版本，用改进的Hilbert变换，效果好一些，供大家参考。(HHT spectrum of the calculation procedures, rilling is not a version of the Hilbert transform used to improve the results better for your reference.)

说明：  此程序包括MATLAB的程序，对大家学习Matlab非常有用，特别适合初学者，欢迎大家下载(This program includes MATLAB program to all of us to learn Matlab is very useful, especially for beginners, are welcome to download)
