“…An estimate of the cumulative distribution function of the delay spread was presented in [2], and lately in [3]. The statistical distribution of the number of peaks and notches, their width and height was studied in [4]. Recently, it has been pointed out that the average channel gain and the delay spread are correlated lognormal variables [3].…”

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.

“…There are very few contributions attempting to define a statistical model for the PL channel, e.g. [4] and [5]. While these contributions represent a step in the right direction, they are still somewhat incomplete, do not allow physical insight, or lack empirical justification.…”

“…III.B in [3]). The work presented in [5] is a very good attempt to classify the widely valuable PL channel realizations with the goal of obtaining a PL channel generator. Nine classes of channels and their respective transfer functions are defined; furthermore, it is observed that peak and notch widths, heights, and numbers of a smoothed version of the measured transfer functions are well described by Rayleigh, triangular, and Gaussian distributions, respectively.…”

We report for the first time some statistical properties of the indoor power line (PL) channel that exhibit some interesting similarities to the wireless channel, although some fundamental differences are also pointed out. In particular, we argue here that, while multipath propagation in wireless channels gives rise to Rayleigh distributed fading, multipath in PL channels gives rise to lognormally distributed fading similarly to shadow fading. We also report for the first time that both channel gain and Root-Mean-Square Delay Spread (RMS-DS) of indoor channels are lognormally distributed, leptokurtic and negatively correlated, thus suggesting that channels that introduce severe multipath are also characterized by large attenuation. These results are used to define a simplified PL channel model useful for comparative analysis of communication schemes and, at the same time, to draw some general conclusions on the design of multicarrier schemes.

The electrical appliances shared with PLC modems in the same powerline network generate noises. Among them, impulsive noises are the main source of interference resulting in signal distortions and bit errors during data transmission. Many impulsive noise models were proposed in the literature. They share the same impulsive noise definition: "unpredictable noises measured at the receiver side". This definition leads to the modelling of thousands of impulsive noises whose plurality would very likely come from the diversity of paths that the original impulsive noise took. In this paper, an innovative modelling approach is applied to impulsive noises which are henceforth studied directly at their sources. Noise at the receiver is considered as the noise model at the source filtered by the powerline channel. Effective in-device sources of impulsive noises are identified and classified into six classes, from which representative noises are proposed. Based on impulsive modelling at source, a receiver side model is finally proposed.
