Abstract

In this paper, we propose a novel multi-band OFDM indoor powerline communication (PLC) system. The physical layer of the proposed system consists of multi-band OFDM, convolutional encoding, Viterbi decoding, and interleaver. p-persistent CSMA/CD is adopted as the MAC layer protocol. A PLC channel model proposed by OPERA (Open PLC European Research Alliance) is considered. Taking account of the characteristics of the powerline noises, an efficient noise detection scheme is applied to dynamically choose among multiple OFDM bands. System performance is evaluated by extensive simulations and the results show that the proposed system can reach a low BER and high system throughput.
