On the statistical properties of indoor power line channels: Measurements and models

In the last years, numerous works have analyzed the statistical distribution of indoor power line channels response. A set of models based on two main approaches, bottom-up and top-down, have been proposed. This work analyzes the statistical distribution of the attenuation and the delay spread of indoor power line channels. First, results obtained from a set of more than 200 channel responses measured in 25 different premises are presented. Then, the suitability of various channel models proposed in the literature is evaluated by comparing their statistical distributions with the one of the measured channels.
