Low-voltage Power Line Channel Modeling And Simulation System

With the rapid development of networks and communication, there're more requirements for wideband communication. Because of the advantages of widely distributed network and none need of rewired, low-voltage power line communication is catching our attention greatly now, which uses the power line as a communication media to create a high speed data channel and supply services such as Home Appliance, Intelligent Building and high speed Internet access. However, the power line network differs considerably from the conventional telecommunication media in topology, physical- and transfers properties. Using this network as a high-speed data communication link, the system design has to consider channel specific demands. So the accurate knowledge of channel specific system demands and the practical models are needed. Moreover, the specify communication technology is critical coordinately. There are beneficial to the research and debug with building a communication simulation system as assistance tool. So we focus our attention on how to build a Plug-and-Play simulator based on software component.This thesis starts with the analysis of the low-voltage power line channel characteristics. Then the noises in the frequency range between 1~ 30MHz are sorted and their properties are given in detail. We also improve the asynchronous impulsive noise by using three-state Markov model, and give all process of establishing the model.Focus on the topic of how to building the Powerline Communication Simulation System (PCSS), we analyze the advantages of reuse and accurate in simulation using component development, and we present the low-cost fast development method Based on the ananlsis of software architectures, formal component model and the reconfiguration of component. Moreover, we make the Software Bus as the main part of system achitecture, which bring the independent between system architecture development and functional component development.Finally we use the CBD (Component-Based Development) method to realize the simulator's framework with the property of Plug and Play as an example. We also present the specify development process and some main modules' data structure under the specification of COM (Component Object Model).
