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 make 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)

为带通滤波器，需设置半阶数、高低截止频率和采样频率。保存为function函数的m文件。rar中为一肌电信号。(For band-pass filter, to be set up semi-order, high and low cutoff frequency and sampling frequency. Save it as a function of m file function. rar for a EMG.)

MATLAB编程百例，一百个例子让您从入门到精通，强烈推荐！(MATLAB Programming 100 cases, 100 examples to let you from entry to proficient, highly recommended!)

This file is the programs of (chapter 4) of book (Modeling the Wireless Propagation Channel a Simulation Approach with MATLAB) which is related to introduction to multipath. It helps you to simulate multipath wireless channel.

这个程序是用matlab绘画三角阵位置和三角阵列接收信号数据的功率密度函数(This program is a triangular matrix using matlab painting has been in matlab run)
