Abstract

Understanding the interference scenario in power lines network is a key step to characterize the power line communication (PLC) system. This paper focuses on the characterization and modelling of the stationary noise in Narrowband PLC. Measurement and analysis of noise is carried out in the Tunisian outdoor Low Voltage (LV) power line network in the frequency band below 500 kHz. Based on existing models and measurements results, a parametric model of noise is proposed; the model parameters are statistically studied.
