Narrowband OFDM Power Line Communication (NB-OFDM PLC) systems are
a key component of current and future smart grids.
NB-OFDM PLC systems enable nextgeneration smart metering, distributed
control, and monitoring applications over existing power delivery
It has been shown that the performance of these systems is severely
limited by impulsive, non-Gaussian additive noise.
A substantial component of this noise has time-periodic statistics
(i.e. it is cyclostationary) synchronous to the AC mains cycle.
In this work, we analyze the cyclic structure of power line noise
observed in a G3 PLC system operating in the CENELEC 3-148.5 kHz band.
Our contributions include:
Through this analysis, we confirm strong cyclostationarity
in power lines and identify several sources of the cyclic noise.
- the characterization of noise measurements in several urban usage
- the development of a cyclic bit loading method for G3
- the quantification of its throughput gains over measured noise.
