效率极高的基于delaunay三角网格剖分程序，只是没有图形输出，可以只将生成文件直接导入matlab中。(Based on highly efficient delaunay triangular mesh generation process, but there is no graphics output, you can only generate documents in directly into matlab.)

Assume that a direct sequence spread spectrum system uses the Barker code of length 7 (N=7) as its spreading sequence. a. Randomly generate 8 symbols (d0~d7) from the set {+1,-1}. b. If each chip of the Barker code is denoted as cj, j=0~6, spread each symbol di by the Barker code. (Please refer to p. 17 of the slides.) Use “stem” to plot the signals before spreading and after spreading

邻域平均法滤波 原图像画面清晰，添加勒椒盐噪声后图像上产生勒明显的黑色斑点（噪声），用不同模板的平滑滤波处理后图像上的噪声消失，但是图像变得模糊，并且，使用的模板越大，对图像的去噪效果越好，同时图像也变得越模糊。 (Neighborhood averaging filter clear picture of the original image, add the Le Salt and pepper noise generated after the image Roming noticeable black spots (noise), smoothing with different template processed image noise disappear, but the images become blurred, and the use of template bigger the better the image de-noising the same time, the image becomes more blurred.)
