An analysis of indoor power line network as a communication medium using abcd matrices effect of loads on the transfer function of power line

Abstract

Power line communication is a technique that uses the available power lines as a communication media. In this paper, the power line is considered as a two-wire transmission line and modeled using the transmission, chain, or ABCD matrices. The line is simulated for different conditions commonly found in practical networks and the salient features discussed in detail. It is found that channel shows a deterministic behavior if the complete network is known a priori. However, in practical cases, discrepancies occur due to unavailability of complete information of the channel. This leads to decreased correlation or/and variable attenuation between the theoretical and experimental readings. The effects of these shortcomings on the efficiencies of discrete multitone system commonly used for power line communications are discussed.
