FM调制解调系统设计与仿真
- 调制解调根据所要调制参数的不同分为调幅(AM),调频(FM),调相(PM)。本设计要求进行FM调制解调进行设计与仿真,得到最后输出波形。具体包括: 1):FM调制解调的基本原理 2):FM调制解调系统设计,要求输入信号叠加白噪声 3):FM调制解调系统仿真,要求通过matlab软件得到输出波形。
基于MATLAB的FM调制实现
- 摘 要 FM属于角度调制,角度调制与线性调制不同,已调信号频谱不再是原调制信号频谱的线性搬移,而是频谱的非线性变换,会产生与频谱搬移不同的新的频率成分,故又称为非线性调制。FM信号是用载波频率的变化表征被传输信息状态的。本课程设计内容:在课程设计中,系统开发平台为Windows XP ,程序运行平台使用Windows XP,程序设计语言采用MATLAB,程序通过调试运行,初步实现了用MATLAB对FM进行调制要求。
