this is a mat lab simulation file including the m file.

说明：  此程序为用matlab实现信号特征提取的实验程序，将待处理的一维时间函数赋给work2中的x1tRE，运行work2即可 (This procedure is used to achieve signal feature extraction matlab experimental procedures, will be dealt with one-dimensional function of time assigned to work2 in x1tRE, you can run work2)

用matlab实现调制，注释详细，BPSK(The modulation with matlab, detailed notes, BPSK)

you can use this matlab code to change image into different color system such as luv, rgb, yuv and lab
