无线衰落信道 在无线移动信道中，信号从发射天线经过复杂的传播环境到达接收天线，接收信号为各反射、衍射和散射分量以及信道噪声的复合，因而会产生严重的失真。另外，移动信道中由于移动台运动或信道环境的改变会使信道特性随时间随机变化，接收到的信号由于Doppler效应会产生更为严重的失真。 (OFDM has superior performance when transmitting high rate data in wireless fading channel.)

使用matlab语言编程求解一维热传导方程(Using the matlab programming language for solving one dimensional heat conduction equation)

提出了一种基于小波变换可抗击几何攻击算法。在水印嵌人 部分# 首先对宿主图像进行小波分解 、 嵌人水印, 再通过余弦变换求得该水印图像的一个特征向量, 利用该特征向量和水印 信息通过12 31 函数生成一个二值逻辑系列, 将该序列作为密钥/ 水印提取部分为# 对待测的图像进行小波变换, 再通过余 弦变换求得待测图像的一个特征向量, 利用该特征向量和密钥通过1 2 4 1 函数提取出水印。(Proposed based on wavelet transform algorithm can be against geometric attacks.# Watermark embedded in the first part of the host image wavelet decomposition, embedded watermark, and then through the cosine transform of the watermarked image obtained by a feature vector, using the feature vector and the watermark information through 1231 to generate a binary logic function series, the sequence as the key/watermark extraction part is# treated transform measured image, and then obtained through the cosine transform the image of a feature vector under test, using the feature vector and the key function by 1241 to extract the watermark .)
