数字水印
- 对原始信号做DCT的算法:Cox 和Piva 等人提出的DCT技术的经典之作。Cox利用随机数发生器产生标准正态序列作为水印信息对图像进行整体DCT变换后,选取除去DC系数之外部分较低频率系数叠加水印信息 Piva则修改整幅图像的中频部分。对原始信号分块后,再作DCT的算法:Hsu和Wu 把图像进行8*8分块,将一个二进制序列作为水印放入DCT的中频区;有些学者则计算整个图像的DCT,把一个实数序列嵌入DCT的中频系数上。选择中频区的好处是一方面尽量减少嵌入信息对图像主观视觉的影响;同时,尽量避

- 在这篇论文中,我们提出一种新的时间偏移估计方法应用于OFDM系统。这里提出的估计是为了避免发生在Schmidl中的时间偏移估计方法中的歧义。通过仿真,所提出方案中的性能以均值和最小均方误差的形式说明。仿真结果表明:它与其它估计器相比在相当大的程度上有更小的均方误差。-In this paper, we propose a new time offset estimation method is applied to OFDM systems. Estimates presented here t
