基于Matlab的模拟通信系统实验设计与仿真

Design and Simulation of Analog Communication Experiment Based on Matlab

针对通信原理课程理论性强、概念抽象的特点,将Matlab的图形绘制和系统仿真等功能应用于通信系统的实验仿真中,设计了基于Matlab的模拟信号传输软件实验,根据模拟通信系统调制解调的原理与方法,以实例验证模拟信号传输过程。学生自己创建基于Matlab的模拟信号传输系统,实时显示各点的时域波形和频谱特性,将课内基础知识与软件系统调试有效地结合,加深了学生对信号传输原理的理解与认识,促进了学生动手能力与创新精神的培养。

Aimed at the profound theories and abstract concepts of communication principle curriculum,the graphics of Matlab and the system simulation are applied to the simulation experiment of communication systems,and an experiment teaching system of analog signal transmission based on the Matlab simulation platform is proposed according to the principle of analog modulation and demodulation.The purpose is to verify the transmission process of analog signal with examples. The students create the simulation process of the signal transmission based on the Matlab by themselves and the waveform and spectrum characteristics of each point can be real- time displayed,which can make the classroom knowledge combined with the debugging software system effectively,deepen students＇ understanding of knowledge and promotes the students＇ ability and innovation spirit.
