  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(This paper describes the principle of DTMF and how MATLAB to generate DTMF signals, mainly related to the telephone dial tone and identification of the basic principles of synthesis of the main method, using MATLAB software, and the FFT algorithm to the telephone communication system, the synthesis and identification of dial tone . And further the use of MATLAB' s graphical user interface simple and intuitive GUI make the analog interface. Able to use a different fundamental frequency matrix synthesis of 0- 9 different button dial tone and can be different correct identification of dial tone to achieve by the dial tone of the process of parsing a telephone number to complete the telephone dial tone system, a simple experiment simulation.-This paper described the principle and how DTMF in MATLAB to generate DTMF)

    说明:  本文阐述了扩展频谱通信技术的理论基础和实现方法,利用MATLAB 提供的可视化 工具Simulink 建立了扩频通信系统仿真模型,详细讲述了各模块的设计,并指出了仿真建模 中要注意的问题。在给定仿真条件下,运行了仿真程序,得到了预期的仿真结果。同时,利 用建立的仿真系统,研究了扩频增益与输出端信噪比的关系,结果表明,在相同误码率下, 增大扩频增益,可以提高系统输出端的信噪比,从而提高通信系统的抗干扰能力。 (This paper describes the theory of spread-spectrum communication technology and implementation methods based on the use of visualization tools provided by MATLAB Simulink to establish a spread spectrum communication system simulation model, described in detail the design of each module, and pointed out that the simulation modeling to note problem. In the given simulation conditions, running a simulation program to obtain the desired simulation results. Meanwhile, the use of the simulation system to study the spreading gain and the relationship between the output signal to noise ratio, results show that the same bit error rate, increased spreading gain can increase the system output signal to noise ratio, thereby enhancing communication system disturbance.)
