通信原理仿真实验系统设计与实现
The design and realization of Correspondence princeple simulation experimental system
Abstract: Correspondence principle curriculum is one of the most important basic courses for the undergraduate of electrical or communication major, but the principle and concept in this curriculum is so abstract and difficult that students hard to understand, it must prepare certain experiment for them. But traditional experimental box which used for experiment project is costly, even have the disadvantages of component crackly and hard to update. For resolving above problems, exploiting a kind of virtual experimental platform is one of the effective ways[12].
This paper combined friendly exploiting interface of VB software with powerful calculating function of MATLAB software, designed and exploited man- robot interaction software simulation system which have the characteristic of friendly interface, easy to operate. Especially introduce ActiveX technology that program by VB and MATLAB software. Further more introduced the design process of the simulation system.

论文摘要：通信原理课程是本科电子类，通信类专业的重要基础课程之一，但是通信原理课程中的原理、概念抽象，理论性强，学生单凭老师上课的讲解难以掌握，这就要求配备一定的实验操作。然而传统的以实验箱作为实验平台的实验教学需耗费大量的实验经费,且具有元件易损，系统升级难和实验效果不理想等缺点。开发一种虚拟的仿真实验平台是解决上述问题的有效途径之一。
本文利用VB的友好开发界面和MATLAB强大的运算仿真功能，将二者相结合，设计和开发出了界面友好、操作简单的人机交互软件仿真系统。并且重点介绍了利用VB和MATLAB进行混合编程的ActiveX技术和该仿真系统的设计与实现过程。
