MATLAB编写的ARMA建模程序，可实现UI打开EXCEL文件，自动选取合适滞后阶数ARMA建模和任意几期预测。(ARMA modeling program written in MATLAB, enabling the UI Open EXCEL file and automatically selects the appropriate number of lags several of ARMA modeling and forecasting arbitrary.)

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,)

以输入和输出信号的统计特性的估计为依据，采取特定算法自动地调整滤波器系数，使其达到最佳滤波特性的一种算法或装置。自适应滤波器可 自适应滤波器 以是连续域的或是离散域的。离散域自适应滤波器由一组抽头延迟线、可变加权系数和自动调整系数的机构组成。(The input and output signals of the statistical properties of the estimators for the basis, take the specific algorithm automatically adjusts the filter coefficients, so as to achieve the optimal filter characteristics of an algorithm or device. Adaptive filter adaptive filterIs continuous or discrete domain domain. Discrete domain adaptive filter is composed of a group of tapped delay line, a variable weighted coefficient and automatically adjust the coefficients of the mechanism.)
