加性高斯白噪声 AWGN(Additive White Gaussian Noise) 是最基本的噪声与干扰模型。加性噪声：叠加在信号上的一种噪声，通常记为n(t)，而且无论有无信号，噪声n(t)都是始终存在的。因此通常称它为加性噪声或者加性干扰。

本文主要阐述了DTMF的原理及如何在MATLAB上产生DTMF信号，主要涉及到电话拨号音合成的基本原理及识别的主要方法，利用 MATLAB 软件以及 FFT 算法实现对电话通信系统中拨号音的合成与识别。并进一步利用 MATLAB 中的图形用户界面 GUI 制作简单直观的模拟界面。 能够利用矩阵不同的基频合成 0 － 9 不同按键的拨号音，并能够对不同的拨号音加以正确的识别，实现由拨号音解析出电话号码的过程，完成对电话拨号音系统的简单的实验仿真。-This paper described the principle and how DTMF in MATLAB to generate DTMF signals, mainly related to the telephone dial tone of the basic principles of synthesis and identification of the main methods, the use of MATLAB software and the FFT algorithm on the telephone communication system dial tone Synthesis and Recognition . And further the use of MATLAB in the production of graphical user interface simple and intuitive GUI interface simulation. Able to take advantage of matrix synthesis of different fundamental frequency 0- 9 different keys of the dial tone and be able to different dial tone to be the correct identification, the dial tone from a telephone number to resolve the process of completion of the telephone dial tone system, a simple experiment simulation
