Channel Characteristics Analysis Of Power Line Communication Based On The Multi-conductor Transmission Line Theory

Broadband power line communication(PLC) systems use the exiting electrical cables to transfer high-frequency communication signals.Its aim is to provide residential or business customers with a high-speed access to communication services such as Internet.In this paper, an outdoor power line communication network structure is introduced and the relevant communication channel model is analyzed.Then,the transmission characteristics of multi-conductor transmission line are discussed and analyzed based on Maxwell's equations and Transmission Line Theory.The classical primary parameters are computed too. To solve the issue of the computation complexity,we present a transform matrix to simply the calculation of the power line communication channel.We present a new approach based on Scattering Matrix for the analysis of power line communication networks.This paper is aimed to complete the analysis of the channel characteristics and promote the process of practicability based on the analysis and computation of the multi-conductor transmission line and communication network.
