摘要
在现代通信系统中,调制技术得到了广泛的应用。调制的类型可分为幅度调制、频率调制和相位调制,每种调制都有各自不同的用途,在通信系统中有很重要的地位。然而如何对这些调制进行分析,在实际中如何判断各种调制设备的工作性能,这成为一个重要的课题。针对这一课题,首先引入了调制这一概念,接着对各种调制技术进行了理论阐述,最后运用MATLAB软件对各种调制进行仿真和模拟,为分析调制和判断设备工作性能提供了可靠的依据。
In the modern communication system,ing technique used widely.However how to make analysis these,how to judge the various operate performance of the equipment,this becomes an important topic.This text aims at this topic,first introduced the modulating concept,immediately elaborated the theory to various modulating technique,the end makes use of MATLAB software to imitate various modulability,provided a dependable basis of the analysis and judgment the work performance of the equipment.
