In this paper, we propose a cyclostationary noise model for narrowband power line communication (NB-PLC) based on frequency-shift (FRESH) filtering. The FRESH filters are designed to shape an input white noise spectrum to a cyclic spectrum extracted from experimental noise measurements. The noise modeling problem is considered as a system identification problem that minimizes the time-averaged mean...
A Smart Grid intelligently monitors and controls energy flows in an electric grid. Having up-to-date distributed readings of grid conditions helps utilities efficiently scale generation up or down to meet demand. Narrowband powerline communication (PLC) systems can provide these up-to-date readings from subscribers to the local utility over existing power lines. A key challenge in PLC systems is overcoming...
This paper addresses power-line communication (PLC) for automated metering infrastructure (AMI) and automated meter reading (AMR) applications in North America, with specific focus on the physical layer. FCC regulations permit powerline communication systems in the US to use the band from 9 kHz to roughly 500 kHz. This paper presents channel and noise characteristics in this band, based on field tests...
