Characterization of in-home MIMO power line channels

Abstract

In this paper a statistical description of in-home MIMO power line channels is derived, based on channel measurements in the 0 to 100 MHz range. In particular, it is shown that the power delay profile has a statistical distribution that could be well described by Weibull and Gaussian distributions. It is also confirmed that the channel attenuation has a linear behavior as a function of the frequency and that the average channel attenuation and the root mean square of the delay spread are inversely correlated. Furthermore, a statistical description of the MIMO power line channel coefficients is provided by using a suitable definition of the correlation among the channel coefficients. Based on the extracted statistical descriptions a new model for MIMO power line channels is proposed. Finally, the consistency between the measured and the generated power line channels is shown.
