随机信号分析远程虚拟实验平台开发

Development of remote virtual experiment platform for random signal analysis

随机信号分析是通信工程专业必修课,但其概念抽象难懂,导致学生学习困难,积极性低。开发了一套随机信号分析远程虚拟仿真实验平台,通过网络实验加深学生对课程的理解,提高学习积极性,培养学生实践能力和分析解决问题能力。远程虚拟实验平台采用浏览器/服务器(B/S)模式,通过MATLAB Web Server代理,使学生可通过浏览器在网络环境下调用进行远程虚拟实验。基于MATLAB Web Server的虚拟仿真实验系统利用了HTML语言方便编写的特点,使学生无需安装MATLAB即可完成实验,降低了教学资源,提高了学生进行实验的时间、地点的灵活性。

Random signal analysis is a compulsory course for communications engineering students, but its content is difficult to understand, resulting in students’ learning difficulties and low motivation. In this paper, we developed a remote virtual simulation experiment platform for random signal analysis. It makes the course understanding of the students deepen through network experiments, and improves learning enthusiasm, practical abilities and analytical problem solving abilities. The remote virtual experiment platform adopts the browser/server(B/S) mode, through the MATLAB Web Server proxy, so that students can call MATLAB functions through the browser in the network environment to conduct virtual simulation experiments. The virtual simulation experiment system is based on MATLAB Web Server and takes advantage of the HTML language, which enables students to make experiments without installing MATLAB. It also reduces teaching resources, and improves the flexibility of the time and place for students to conduct experiments.
