Statistical model study for Narrowband Power Line Communication Noises

Noise is one of the main problems for the Power Line Communication (PLC) system. Noise parameters vary from country to country. They depend on time, place, load types, power line topology and mains voltages. This is annoying issue for researches who try to make a mathematical model to understand noise characteristics. Therefore a lot of measurement campaigns should be done before setting up a mathematical model and also model has to include statistical studies. The subject of this paper is the development of a statistical noise model for Narrowband PLC in the low voltage network. Noise model parameters were derived from measurements of the mains voltages in using Data Acquisition card (DAQ) and a digital signal processing program. Results of this model obtained very akin to present situations. Contribution of this study is that it helps the researcher to work independent of power line voltage and frequency.
