Unified background noise model for Power Line Communication

In Power Line Communication, it is necessary to have a model of noise to optimize transmissions and to compare different methods in a noise controlled environment. This communication presents a new method to estimate more efficiently the background noise parameters of a model extracted from the literature. The new estimation leads to more robust model parameters evaluation regarding narrowband interference. The effort done regarding to this noise source permits to highlight the dependence of the background noise to the mains period. This allows defining a new unified model, taking into account the dependence to the absolute value of the mains voltage. This provides a new background noise function verified and useful for low and high data rate technologies and for further noise studies.
