doi:10.11930/j.issn.10.11930.2015.8.146

Abstract

Abstract: Complex noise is one of the main reasons for hindering the development of power line communication technology. Accurate noise simulation is important for the further development of power line communication. The noise measurement circuit is built and the channel noise is measured in this paper. The measured channel noise is analyzed with Fourier transform and time-frequency analysis, and the sine components of three channel noises are obtained. Finally, three PLC channel noises are simulated by superposing different frequency sine waves. The experimental results show that the simulated channel noise and the measured channel noise have high consistency.

Key words: power line communication, channel noise, Fourier transform, time-frequency analysis
