PLC channel characterization up to 300 MHz: Frequency response and line impedance

摘要

We investigate the statistics of the in-home power line communications channel in the broadband frequency range up to 300 MHz. The analysis is based on the results of an experimental measurement campaign in Italy during which we acquired more than 1300 channels. Firstly, we focus on the channel frequency response. We study the statistics of the amplitude (in dB). In particular, we infer the normal distribution of the quantity. Furthermore, we examine the statistics of the phase. Then, we study the line impedance. We investigate the statistics of the resistive and reactive component of the line impedance and their relation. Finally, we perform the joint analysis of the line impedance components and the amplitude of the channel frequency response.
