说明：  尽管瑞利和莱斯分布确实能够在很多情况下对信号通过衰落信道后的包络进行很好的建模，然而，在实际的无线环境测试中，发现Nakagami分布提供了更好的与实际测试的匹配度。(Although Rayleigh and rice distribution can model the envelope of the signal after passing through the fading channel in many cases, in the actual wireless environment test, Nakagami distribution is found to provide a better match with the actual test.)

目标检测（小目标或点目标检测，基于数学形态学的目标检测）(Target detection (small target or target detection, target detection based on mathematical morphology))

说明：  实验目的 本次实验与书中第二章及3.2节的部分内容有关，包括以下几个部分： （1）开始使用MATLAB （2）显示图像，理解图像的模型 （3）使用图像的不同格式，理解图像压缩的意义 （4）对图像做简单的操作 本次实验需要熟练使用以下几个MATLAB命令： imread, imwrite, imshow,figure (Experimental purposes of this experiment with the book, chapter and part of the contents of 3.2, including the following sections: (1) start using MATLAB (2) show the images, understanding image model (3) the use of images in different formats, understand the significance of image compression (4) on the image to do a simple experiment needs to operate the skilled use of the following MATLAB command: imread, imwrite, imshow, figure)

编写的EMD分解程序，希望能帮助到需要的人(Preparation of EMD decomposition process, hoping to help people in need)

matlab下利用s-function实现rs232编码、解码及通讯的实例程序。需要在matlab下利用mex编译使用（参见s-function用法）(matlab using s-function to achieve rs232 encoding, decoding and communication procedures of the examples. Need to use matlab using mex compiler (see the use of s-function))

说明：  为MATLAB中的图形增加标签，从而可以有效地表示图形意义，防止读不懂图的情况( BWLABEL supports 2-D inputs only, whereas BWLABELN support any input dimension. In some cases you might prefer to use BWLABELN even for 2-D problems because it can be faster. If you have a 2-D input whose objects are relatively "thick" in the vertical direction, BWLABEL will probably be faster otherwise BWLABELN will probably be faster.)
