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：  Haskell 中文教程1-3章(flw译) 纯粹的函数型编程语言。以著名逻辑学家 Haskell B. Curry 的名字命名。 最初的目的是想要设计出满足下面这些要求的语言： 1，它必须能够适合教学、研究、应用开发，包括一些大系统的构造。 2，它必须能够使用形式语言来准确描述。 3，它必须是自由免费的，任何人只要愿意都可以获取、使用和再次发布它。 4，它必须建立在大家一致认可的基础上。 5，它应该能够消除目前的函数型编程语言的差异。 (Haskell Chapter Directory 1-3 (flw translation) purely a function-based programming language. Famous applicability Haskell B. Curry named. The initial aim was to get below designed to meet the language requirements : 1, it must be suitable for teaching, research, application development, including the construction of large-scale systems. Two, it must be able to use formal language to accurately describe. 3, it must be free free of charge, to anyone who can access, use and release it again. 4, it must be built on consensus on the basis of recognition. 5, it should be able to eliminate the current function-type programming language differences.)

雷达通信一体化系统，针对非波动目标以及波动目标的雷达探测性能分析。(he dual-frequency MPPSK-MODEM platform is a flexible one. When ranging accuracy request is low or platform is particularly affected by power limitations, the platform would perform both data transmission and range measurement with single frequency modes. In this paper, the ranging resolution of MPPSK pulse waveforms with the match filter and impacting filter processing method are discussed, respectively. Also, the selection of MPPSK modulation parameters for ranging is considered. In particular, requirements that allow for employing such special parameter values for range measurements with high accuracy and high range are investigated. Moreover, high repetition frequency (HRF) bi-phase code MPPSK pulse train base on m sequence are presented, the ranging accuracy of the proposed signal with the match filter processing method is deduced. In addition to theoretical considerations, the paper presents system simulations and measurement results of single-frequency MPPSK intergated systems, d)
