这是一个关于PSK和LDPC码相结合的运用程序，很有参考价值。(This is an LDPC code on the PSK and the use of a combination of procedures, a good reference.)

说明：  利用matlab，读入一幅图片，输出它的7个不变矩。。。。(Using matlab, read a picture, the output of its seven invariant moments. . . .)

lear N = 10^5 EB_NO = [-1:30] liu1 = zeros(1,N) liu2 = zeros(1,N) for ii = 1:length(EB_NO) m= (2*(rand(1,N)>0.5)-1) + j*(2*(rand(1,N)>0.5)-1) s = (1/sqrt(2))*m normalization of energy to 1 n = 1/sqrt(2)*[randn(1,N) + j*randn(1,N)]

用黄金分割法来求解函数的极小点，不用求函数的导数，只需进行迭代即可,非精确线搜索技术用于解决极值区间(Golden section method to solve the minimum point of the function, do not seek the derivative of a function, simply iteration can be inexact line search techniques for solving extremal interval)

一种改进的混沌算法，结合进化算法进行改进,利用logistic映射进行改进(An improved chaotic particle algorithm to improve the diversity of PSO)

matlaba的图像匹配，进行图像的处理。(matlaba image matching, image processing.)
