Matlab在通信原理中的应用

摘要 Matlab是集数值计算,图形绘制,图像处理及系统仿真等强大功能于一体的科学计算语言。随着Matlab与Simulink通信,信号处理专业函数库和专业工具箱的成熟,它们在通信理论研究,算法设计,系统设计,建模仿真和性能分析等方面的应用也越来越广泛。
本文首先介绍了Matlab软件和通信原理的相关知识,而后主要利用了Matlab图形绘制和系统仿真功能,通过引用实例的方式介绍了Matlab在通信原理中的应用:符号微积分运算、绘周期波的频谱、模拟调制、数字调制,眼图观察,simulink仿真正弦信号。

The application of MATLAB munication theory
Abstract Matlab is one kind of puting languages which set some stron- g functions such as numerical calculation, graphics rendering,image processing ,system simulation and so on in the Matlab and munications,sig-
nal processing professional function library and professional toolbox being mature, they e more and more widely applied munication theory research,algorit- hm design,system design,modeling simulation and performance analysis.
This paper firstly introduces the Matlab software munication theory, then it introduces the application of Matlab munication theory by quoting exam- ples .It mainly uses Matlab graphics and system simulation function such as symbol calculus operations,drawing spectrum of periodic wave, simulated modulation,digital modulation,eye chat observation and simulinking sine signal.
