Narrow-band interference error correction in coded OFDM-based PLC systems

Abstract

This work analyzes different error-correcting schemes for combating the effects of narrow-band interference in coded orthogonal frequency-division multiplexing-based narrow-band power line communication systems. In this sense, we analyze an error-correcting scheme widely acclaimed in the literature, which is constituted by the concatenation of a Reed-Solomon (RS) code, a convolutional code and an bit interleaver, and an alternative error-correcting scheme with less computational complexity composed of an RS code concatenated with a short block code. Base on a comparative performance analysis of both error-correcting schemes in terms of bit error rate, we conclude that the alternative error-correcting scheme offers satisfactory performance in terms of bit error rate and considerable computational complexity reduction when compared to the usual one.
