NB-PLC channel: Estimation of periodic impulsive noise parameters and mitigation techniques
(چکیده مقاله) :
Abstract :
Narrowband Power Line Communication (NB-PLC) plays a key role in the deployment of smart grid, since it is a
widely spread technology for smart grid applications and systems, like the Advanced Metering Infrastructure
(AMI) system. In this paper, we study the characteristics of the NB-PLC channel and noise. A method is proposed
to estimate the occurrence and duration of the dominant category of noise, the periodic impulsive noise, which
greatly degrades the signal quality. A technique is proposed to mitigate the noise effect, with the use of Luby
Transform (LT) codes. The proposed scheme exploits the features of the dominant noise on the NB-PLC channel
and mitigates its effect especially in highly noisy environments. An estimation algorithm of the burst time
occurrence and its duration is introduced. The system can estimate these parameters with an accuracy in the
range of 10−4 and it can work even without channel state information. The proposed scheme is compared to two
popular NB-PLC technologies, namely the PRIME and G3-PLC, whereas the results show that it can be very
effective under severe noise conditions.
