Narrowband stationary noise characterization and modelling for power line communication

This paper presents an appropriate model for the narrowband stationary noise observed on the Power Line Communication (PLC) channels. Extensive measurements were carried out in the indoor low-voltage (LV) power line network in order to investigate the stationary noise characterization and modelling in the low frequency range. A parametric model is proposed for the noise power spectral density (PSD) in the CENELEC/FCC/ARIB bands and the model parameters are statistically studied. This statistical model is useful for generating stationary noises at low frequencies in order to assess the performance of communication chains and to improve the design of narrowband PLC systems.
