Abstract

With the development of the smart grid, power line communications (PLC) is becoming more and more important. Compared with traditional modulation, Orthogonal Frequency Division Multiplexing (OFDM) has the advantages of the full use of spectrum, inherent robustness against narrowband interference, and excellent robustness in multi-path environments. This article is devoted to compare FFT-based OFDM in Broadband-PLC (BB-PLC) with in Narrowband-PLC (NB-PLC), conduct experiments to get the PLC channel characteristics and give some advice to the standard in progress.
