ADDAwatermarking
用MATLAB实现了该算法，并对所实现方法进行了验证，在步骤（3）中则给出了求出滤波器类型及参数的方案，并进行验证，在步骤（4）中通过MATLAB的AWGN函数等相关知识实现了AWGN信道的仿真。
本文首先介绍数字水印和音频水印的相关概念和发展概况，接着介绍了完成仿真工作所需的基础知识，之后提出DA/AD变换的仿真实现，(Using MATLAB realization of the algorithm, and the realization method of authentication, in step (3) in the given filter type and parameters to derive the program and verify, in step (4) through MATLAB-AWGN function and other relevant knowledge to achieve the AWGN channel simulation. This paper first introduces the digital watermarking and audio watermarking-related concepts and developments, and then introduced a complete simulation of the basic knowledge required, after the DA/AD conversion of the simulation,)
