基于MATLAB信号源滤波器和信号的调制与解调毕业论文.docVIP

摘 要 通信技术是当代最主要的三大技术之一，其原理内容丰富且抽象，怎样让这门课程学习起来更加透彻的接受，是各高校及相关学习者的热点话题。由通信原理的抽象特点提出了使用MATLAB仿真进行可视化。在通信系统的相关知识学习中引入MATLAB仿真软件可以弥补传统教学的不足，同时也可以让学习者在边练边学边设计的环境下，完成对通信系统枯燥的理论知识的学习。通过大量实践已经证明，它既可以在学习中让抽象的理论更加形象直观，而且还可以避免大量的复杂计算，使学习效果得到明显的改善。本文具体讲解了应用MATLAB语言以及仿真处理技术确保图形结构样式简单易懂，为后期的系统学科发展起奠基作用。本设计主要阐述了基于 MATLAB 工具的建设通信系统概念模型的原理以及具体的讲述了几个主要的通信系统的模块，对信号源、滤波器和信号的调制与解调作用进行分析。 关键词：MAT LAB；Simulink；抽象的通信系统理论；调制；解调Abstract ICT is one of the three most important contemporary art, rich and abstract principle, this course to learn how to make it more thorough acceptance, universities and related learner is a hot topic. Abstract characteristics of the communication theory proposed the use of MATLAB simulation for visualization. The introduction of relevant knowledge and learning communication system MATLAB simulation software can compensate for the lack of traditional teaching, but also allows learners to learn while practicing under the design environment, complete communication systems boring theoretical knowledge. Through a lot of practice has proved that it can make in learning more visually abstract theory, but also to avoid a large number of complex calculations to make learning effect has been significantly improved. This paper explains the application of MATLAB language and simulation processing technology to ensure that the graphic structure style is simple and easy to understand,for laying the system of discipline development.This design mainly expounds the principle of the construction of communication system and conceptual model of MATLAB tools and specific about the communication system of several major modules based on modulation and demodulation signal source,filter and signal analysis. Key words: MATLAB; Simulink; abstract communication systems theory; modulation; demodulation 目 录 摘 要 I Abstract II 1 绪论 1 1.1 通信系统研究的背景 1 1.2 在通信系统中引用MATLAB的必要性 1 2 MATLAB/simulink的简介 3 2.1 MATLAB系统的简介 3 2.2 Simulink系统的简介 3 2.3 MATLAB软件的操作 3 3 通信系统仿真模型的设计 7 3.1 通信系统的基本模型 7 3.2 通
