通信中的QPSK相位调制建摸，其中考虑了多径和高斯的影响(Communication QPSK modulation phase modeling, which takes into account the multi-path effects and Gaussian)

implementation particle swarm optimation in C++

matlab，把文件解压后放入matlab的默认文件夹里，一般是（C:MATLAB7work）。在matlab主窗口中输入命令ima=imread( C:MATLAB7work1.jpg )，然后输入命令[P,U,iter]=GPAS2(ima,2)，即可。绝对好运行(matlab, matlab to unzip the files into the default folder, usually (C: MATLAB7 work). In the matlab main window, type the command ima = imread (' C: MATLAB7 work 1.jpg' ), and then enter the command [P, U, iter] = GPAS2 (ima, 2), can. Definitely a good run)

代码已经整合到文档，直接copy到matlab命令行，运行即可。用阈值分割、形态学处理等解决了很多很难分割的图像。(The code has been integrated into the document, direct copy to the Matlab command line can be run. Thresholding and morphological processing to solve many difficult to split the image.)
