An analysis of the broadband noise scenario in powerline networks

Abstract

Opposite to many other communication channels the powerline channel does not represent an additive white Gaussian noise (AWGN) environment; in the frequency range from some hundred kilohertz up to 20 MHz it is mostly dominated by narrow-band interference and impulsive noise. After a basic classification of the different types of noise the properties of background noise and narrow-band interference are discussed. Spectral analysis and time domain analysis of impulse noise gives some figures of the power spectral density as well as distributions of L noise f , I impulse noise ; J , . . .
