Communication Experiment System Based On Virtual Simulation Technology, Design And Realization

With the deepening reform of higher education and the rapid expansion of enrolment, The nation's universities has generally fallen into difficult position in experimental teaching which mainly manifests in lack of hardware facilities , backwardness of teaching methods and contents, and limiting teaching by time and space , ect. Under the premise of rapid development in computer and multimedia technology, making full use of virtual experiment system of computer resources is becoming an ideal choice of solving the problem and improving the quality of experimental teaching.This paper, analyzing present Virtual Experiment development status and trends on the basis of the request for experimental teaching and existing virtual experimental systems, contraposing the insufficiency of experimental teaching request and existing hypothesized experimental system, and because of the present virtual simulation system that is mostly created based on Matlab which lacks good Interactivity, therefore combining VC object-oriented visualization programming and Matlab good data processing, proposes a designning plan of"based on VC mobile communication hypothesized simulation experiment system"and has raised concrete research and design to the key technologies.The paper firstly introduces the significance of the research,the present status at home and abroad, the establishment and simulation of multi-dimensional numeral modulation system as well as the structure and content of the article. Secondly, the article presents the development of virtual simulation experimental system, profounds a virtual simulation system overall design achieved in the paper. It also puts forward to the procedures developing hypothesized simulation software using VC and MATLAB, particularly describing the process of the hypothesized simulation modelling. At the same time, this article discusses VC and MATLAB connection programming technology. Furthermore, the features of the simulation software MATLAB and its integrated development as well as its practical environment, the features of Simulink and its working environment, Simulink communication simulation module library along with its modeling and simulating methods are introduced here. Basing on using VC and Simulink to simulate simulation modeling, simulation experiment and simulation analysis are mainly done in this article. At last, the paper Introduces the feature of MATLAB simulation software and its integrated development environment, the feature of the Simulink and its working environment, and Simulink communication simulation modules and Simulink in modeling and simulation methods.
