对于图像进行ANORLD变换，在图像嵌入水印的过程中，可以对要嵌入的水印图像先进性置乱操作，可以有效地抵抗剪切攻击(For images ANORLD transform, watermark embedding in the image of the process, can the watermark image to embed the advanced nature of the scrambling operation, can effectively attack the shear resistance)

说明：  这是模型参考自适应的一个m文件，希望有用(This is a model reference adaptive m file, hope that useful)

Simulink是MATLAB最重要的组件之一，它提供一个动态系统建模、仿真和综合分析的集成环境。在该环境中，无需大量书写程序，而只需要通过简单直观的鼠标操作，就可构造出复杂的系统。Simulink具有适应面广、结构和流程清晰及仿真精细、贴近实际、效率高、灵活等优点，并基于以上优点Simulink已被广泛应用于控制理论和数字信号处理的复杂仿真和设计。同时有大量的第三方软件和硬件可应用于或被要求应用于Simulink。(Abstract: In the development of communication technology, communication system simulation technology is a technical focus. This paper will focus on simulation of communication systems in the modem system and the basic principles of anti-noise performance and MATLAB simulation software platform to achieve some common analog modulation. The most important of the most commonly used analog modulation is the sine wave as a carrier perspective modulation and amplitude modulation. Common AM (AM), with bilateral (DSB), residual sideband (VSB) and single sideband (SSB) modulation, )
