A Systematic Approach to Analyzing Multipath Parameters From PLC Channel Response

The reliable analysis of the power-line communication (PLC) channels is necessary to model, design, and implement a well-matched PLC transceiver. However, a typical power-line channel has not yet been properly described since it is difficult to analyze the time- and space-varying characteristics. Consequently, it is still very important to measure, analyze, and model the power-line channel well. In this paper, focusing on the analysis of the channel response, we suggest a novel systematic approach to analyzing the multipath parameters. The proposed approach is convenient in that we can systematically find the multipath parameters like time delays and attenuation factors including magnitudes and phases from the measured complex impulse response. The simulation and experimental results show that the proposed approach is valid and appropriate for a typical power-line channel.
