Simulation On Video Communication Based On Object-Oriented Technology

ABSTRACT In recent years,with the development of multimedia and IP communication,video,image,computer vision,multimedia database and computer networktechnology have com out in every aspect of national economy and social life,the video transmission that is in key position, especially the video transmissionin wireless channel,has gradually become the new demand of wirelesscommunication business with the the increase of wireless communicationbandwidth and the improvement of data transiation. The development ofcomputer science and the extension of application domain have also putforward more and more high requirement for computer application technology.Especially after the rapid development of computer hardware, the computersimulation technology are improved greatly.Object-oriented technology is anew thought in software development, has been applied in many area ,andadopts object class and inheritance. So object-oriented simulation theorywhich combines with object-oriented htought is the research hotspot now. To study transmission capability of the modulation and channel coding intypical channel,establish a characteristic wireless video communicationmodel,realize the real-time play. For some character of mobile channel such as multiway fading effectwhich causes long-burst error, It establishes an three-state markov model ,acombinational channel(RAYLEIGH+RICIAN+AWGN channel),and a videocommunication model based on MARKOV and combinational channel. To realize the compressed video source transmission,design interfacefunction over some simulation enviroment.
