dcthide
dct隐写技术matlab实现资料。算法原理:通过在一个图像块中调整两个DCT系数的相对大小,隐藏秘密信息。
将载体图像分为8×8的块,做二维DCT变换
用来表示选中的两个系数的坐标对于第i bit秘密信息
if(要隐藏信息‘1’)
make
else

逆DCT变换,还原图像
(dct steganography matlab implementation information. Algorithm principle: an image block by adjusting the relative size of the two DCT coefficients, hidden secret information. The vector image is divided into 88 blocks, making two-dimensional DCT transform coefficients used to represent the coordinates of the selected two for the first i bit secret information if (to hide information ' 1 ' ) make else make the inverse DCT, restore image)

PLRandom-zxk
电力线通信多径信道模型-Manfred Zimmermann模型,多径效应的传递函数H(f)可以用N条传输路径的叠加以及含有频率f、延时τ、距离d的方程来表示:
H(f)=∑g_i *A(f,d_i )*e^(-j2πfτ_i )
式中,i 为路径号, g_i为路径 i的加权系数(包含了传输系数和反射系数的作用),A(f,d_i )为衰耗,其大小由长度、频率决定,τ_i是每条路径上的延时。
