Abstract Share this page

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.
