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 .)

8.6
主要用途是对抗多径衰落。由于多径衰落的存在,使得同一个帧由于路径不同,到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰,影响 性能。另外,由于有了循环前缀,使得IFFT FFT操作把原来的线性卷积变成循环卷积,大大简化了相应的信号处理复杂度(Graduate study do not to upload copyrighted controversial content and Trojan code and agent software to access foreign sites)
