光载无线电系统实验方案设计与教学实践

本文介绍光纤通信实验中安排的光载无线电的综合性设计性实验项目。该实验采用学生自主设计的模式,实验教学环节有:核心模块设计、自主系统搭建、传输信号分析、参数优化和总结汇报及考核等,可以在仿真软件上对自行设计的系统进行测试及优化。教学实践证明,大部分学生能自主设计各具特色的光载无线电系统,在波分复用单通道下行链路中,速率达到1Gbits/s;通过实验学生能学到科学研究的方法,进而锻炼了创新意识与创新实践能力;该实验方案对于高校实验室教学改革具有较好的借鉴意义。

Design and Teaching Practice of Experimental Scheme for Radio-over-Fiber System

A comprehensive design experimental project of radio-over-fiber is arranged in the optical fiber communication experiment in this paper.The experiment is designed by students themselves.The main teaching modules include core module design,system construction by themselves,transmission signal analysis,parameter optimization,summary report and assessment.The system can be tested and optimized on the simulation software.Practice has proved that most students can independently design their own Radio-over-Fiber systems.In the WDM single-channel downlink,1Gbits/s of information rate can be achieved.And scientific research methods can be learned.And then the sense of innovation and innovative practice ability is developed.This experimental program has a good reference for the reform of university laboratory teaching.
