仿真陆地移动卫星通信信道模型——Lutz模型(simulating channel s model of satellite mobile communication ——Lutz model)

基于压缩传感的匹配追踪重建算法研究。给出了OMP的一种改进方案。OMP算法本身耗时过长速度过慢，本文的改 进方案将图像进行分块后再处理，从而大大降低了OMP算法每次迭代的矩阵规模。 实验结果表明，该方案在不明显降低重建效果的同时提高了运算速度。(Matching track reconstruction algorithm based on compressed sensing)

To find location and stitch the break links and transmit the data sender to reciver

图像空域锐化增强，用matlab分别实现Roberts、Sobel、Priwitt算子的锐化处理，以及实现拉普拉斯图像和原始图像叠加的增强处理(Image airspace sharpening, respectively, to achieve with matlab Roberts, Sobel, Priwitt operator sharpening, and achieve enhancement Laplace image and the original image overlay)

说明：  matlab 使用自定义函数，进行幂函数拟合。(use a custom matlab function for fitting the power function.)

I found it s so terriable to search Fisher s exact test well written in matlab. So here is the file that produces p-value efficient, with good examples, easy for beginner s without any knowledge about theory behind.

matlab语言编写 新三步搜索算法 ，希望大家有用(New Three Step Search Algorithm)

采用两种观测器对卫星故障诊断和隔离仿真，达到了很好的效果。(FDI of Satellite simulink using two observers and parity space)

基于A* 算法的简单寻路算例，点击A star search 运行(A* algorithm is based on a simple numerical example wayfinding, click on A star search operation)
