AM传输系统及仿真

AM 传输系统及仿真AM 传输系统摘 要如今的通信技术不断提升，通信专业的建设也有了很大的改变，尤其是要求学生有着更强的综合运用所学知识能力。通信这个专业作为电信是从 19 世纪初开始，而到了如今 21 世纪的无线通信，AM 光纤通信、调制与解调、网络新科技、无线电传播等等这些发展更是一日千里。在此我们选择了一个课题 AM 传输系统对此进行分析其的系统的组成以及调制解调过程，采用的是软件 System View，进行 AM 传输仿真；利用 System View 仿真工具对系统的频谱以及波形进行分析比较；验证了仿真系统的正确性，加深了对常用模拟线性调制解调系统的理解。关键词：System View AM 调制 通信系统AM Transmission SystemAbstractToday's communication technology is constantly improving, and the construction of the communication major has also changed a lot, In particular, students are required to have a strong comprehensive use of the knowledge of the ability.Communication as telecommunication began in the early 19th century. Nowadays, in the 21st century, wireless communication system composition, modulation and coding, network technology, new wireless communication technology and so on are developing rapidly.In this paper, we analyze the composition and demodulation process of a common analog linear modulation system. We choose system view to complete the simulation of AM / coherent demodulation in analog linear modulation system;The system view analysis tool is used to analyze and compare the waveform and spectrum of the system, which verifies the correctness of the system simulation and deepens the understanding of the commonly used analog linear modulation and demodulation system.Key word : AM modulation communication system System View目 录1 前言 ........................................................................ 1 1.1 本设计的目的、意义 以及应达到的技术要求 ............................... 1 1.2 本设计 的发展概况及存在问...
