“…In [4], the characteristic and mathematical model of colored background noise was studied based on neural network and it showed that artificial neural network modelling method was efficient for modelling the colored background noise in PLC systems. In [5], some circuits were set up to measure the noise on the power line and then the power line colored background noise model, narrowband noise model and burst noise model were set up respectively based on the measured noise data.…”

Power line communication (PLC) systems are contaminated with complicated noise. Five types of noise in power line communication systems are introduced in this paper. According to their properties, these noises are mainly divided into two types that are background noise and impulsive noise. Noise modelling approaches for background noise and impulsive noise are reviewed in this paper. A frequency-domain based model is applied to describe the properties of background noise and a frequency decreasing power spectral density (PSD) is revealed based on this model. The values of PSD are between-140dBm/Hz and-80dBm/Hz. A time-domain approach which is based on partitioned Markov chain is applied to describe the time behaviour of impulsive noise. Simulation results showed this model is suitable for the description and modelling of impulsive noise. This model revealed that impulsive noise rarely exceeds a few milliseconds.

In a communication system, noise has always been considered as a serious cause of error. Although most common noises can be modeled by well-known Gaussian distributions, some communication systems experience other types of noise. Power Line Communication (PLC) is one of these systems which run on a difficult medium since it uses the preexisting power line network for transmission. PLC experiences several different types of human-made and natural noise which are mostly impulsive and cannot be modeled simply by Gaussian. Different statistical models are used for characterizing the impulsive noise of PLC systems in the literature. The purpose of this study is to go over the impulsive noise models previously presented in order to have a contribution to this hot topic. We point out the similarities and differences of the models, namely Middleton Class A, Bernoulli Gaussian and Alpha Stable statistical models. It is presented that all have heavy tails which make them appropriate for impulsive noise. Although Middleton Class A is more generic, Bernoulli Gaussian model is wide enough and can be preferable because of its compact simple form especially when analytical results are needed.
