On PLC channel models: An OFDM-based comparison

Abstract

In this paper, some indoor PLC channel models are compared from an OFDM communication system perspective. Firstly, three representative models have been selected to generate channels in a statistical way, which are later included in an OFDM system simulator designed according to Homeplug-AV parameters. Secondly, the system performance is analyzed for the three cases of channel models and is compared to the one obtained for a set of almost 200 measured channels. An additional study about the Gaussian nature of the linear distortion in the OFDM system caused by the channels (modeled and measured) is presented.
