Abstract: Under the background of new engineering courses, colleges and universities have put forward higher requirements for the innovation and comprehensiveness of the experimental teaching of communication principles. Aiming at the existing problems in the experimental teaching of communication principles, an experimental simulation platform based on LabVIEW is designed and implemented. Taking DSB and 2DPSK experiments as examples, the specific design process and implementation of the experimental simulation platform are introduced. The experimental results show that the combination of virtual simulation platform based on LabVIEW and traditional experimental platform is helpful to improve the practicality and interest of teaching, enhance students' knowledge application ability and innovation ability, and meet the needs of new engineering development.
Keywords: LabVIEW; communication principle; virtual instrument; simulation platform

虛拟实验室最早在1989年由美国的William Wolf教授提出,用来描述一个计算机网络化的虚拟实验室环境[1]。学生做实验时可以不受时间和地点的限制,只需一台与该实验室系统网络连接的计算机,便可通过局域网进行相关实验[2]。
随着LabVIEW、MATLAB、System View等虚拟仿真软件的开发与应用,使得通信原理实验变得丰富[3,4]。为了研究通信原理实验的发展研究现状,通过在CNKI数据库中,以“通信原理实验”为检索词,检索1991年至2021年通信原理实验的研究文献,共得到文献数据信息467条,年份与发文量之间的趋势如图1所示,主题关键词与发文量之间的柱状图如图2所示。由图可知,2005年以后,随着信息化的快速发展,高校对通信原理实验不再局限于传统的教学模式,开始进行改革与创新,而通过图1(b)的主题关键词与文献数量之间的分布情况可知,“虚拟仿真”“LabVIEW”“MATLAB”“System View”等词的高频率出现,说明“新工科”背景下,通信原理实验设计进行了较多的改革与创新。……
