PSK系统半解析仿真 matlab符号间干扰ISI与误码率的关系 与Eb/No的对应关系(Correspondence between PSK system semi-analytical simulation matlab inter-symbol interference ISI and BER with Eb/No)

本文提出了基于二维混沌映射的数字图像水印算法，混沌具有随机性、似噪声及对初始条件的极端敏感性等特点。将经过二维混沌映射置乱后的数字水印信号嵌入图像小波域的低频系数，实现了数字水印的隐蔽性、保密性和稳固性；利用二维混沌映射Arnold变换对水印信号进行置乱，不仅增强了水印信号保密性，同时有效提高了视觉上抵抗图像剪切攻击的能力(failed to translate)
