LDPC编译码仿真。部分迭代编码，不限定H矩阵类型，SPA算法译码。(LDPC codec algorithm in AWGN channel。)

多输入多输出的小波网络模型，需安装matlab神经网络工具箱用的是青岛海洋大学学报上那篇论文的模型,嵌入了开发的初始化算法，程序里有较为详细的说明，很好用(Multiple-input multiple-output wavelet network model, the need to install matlab neural network toolbox is used Qingdao Ocean University Journal article thesis model, embedded in the development of the initialization algorithm, the procedure has a more detailed explanation, very good use)

功率控制函数代码描述细节。博弈论的应用。。。。。。。。。。。(Power Control)

％ 文件名：randlsbget.m ％ 程序员:余波 ％ 编写时间:2007.6.25 ％ 函数功能: 本函数将完成提取隐秘于上的秘密信息 ％ 输入格式举例:result=( scover.jpg ,56, secret.txt ,2001) ％ 参数说明: ％ output是信息隐藏后的图象 ％ len_total是秘密信息的长度 ％ goalfile是提取出的秘密信息文件 ％ key是随机间隔函数的密钥 ％ result是提取的信息 function result=randlsbget(output,len_total,goalfile,key) ste_cover=imread(output) ste_cover=double(ste_cover) ％ 判断嵌入信息量是否过大 [m,n]=size(ste_cover) frr=fopen(goalfile, a ) ％ p作为信息嵌入位计数器将信息序列写回文本文件 p=1 ％ 调用随机间隔函数选取像素点 [row,col]=randinterval(ste_cover,len_toal,key) for i=:len_toal if bitand(ste_cover(row(i),col(i)),1)==1 fwrite(frr,1, bit1 ) result(p,1) else fwrite(frr,0, bit1 ) result(p,1)=0 end if p==len_total break end p=p+1 end fclose(frr) ()
