Here s is a code for alamouti scheme having transmitter diversity! :) njoooy!

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 )

森林火灾仿真，元胞自动机，可视化设计，非常经典(Forest fire simulation, cellular automata, visual design, very classic)

说明：  希尔伯特黄变换，提供了EMD分解，希尔伯特包络提取，希尔伯特边际谱绘制(including EMD and envlop extraction using Hilbert and marginal spectrum)

说明：  更新部分 1、自适应算法采用参考文献[2]的NLMS算法，收敛速度更快，所需训练次数更少。 2、自适应收敛步长在(0,2)之间存在较优取值，Lorenz序列为0.6。(update an adaptive algorithm reference [2] NLMS algorithm, convergence faster, less the number of required training. 2, adaptive step in the convergence of (0,2) between the optimum value, Lorenz sequence of 0.6.)

Digital image processing is the processing and display of images. Emphasis is placed on the modification of the image. There are three main categories of image processing
