Impulsive noise characterization at source

Abstract

The noise characteristics of an indoor powerline network strongly influence the link capability to achieve high data rates. The appliances shared with PLC modems in the same powerline network generate noises, among them the impulsive ones which are the main source of interference which causes signal distortions leading to bit errors while data transmission. Many models were proposed in the literature. They shared the same impulsive noise definition: unpredictable noises measured in the receiver side. Authors are, consequently, confronted to model 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 modelisation approach is applied to impulsive noises which are henceforth studied directly at their sources outputs. Noise at receiver would be simply the noise model at source filtered by powerline channel block.
