Abstract :
A combination of OFDM modulation with fountain and permutation coding for power-line communications is investigated in this paper. A process to identify and mitigate the errors caused by impulse noise and narrow-band interference is proposed. We further present the decoding bit error rate and redundancies introduced by this scheme. Due to its simplicity and low encoding/decoding complexities, this scheme therefore can be suitable for a simple but robust OFDM-based power-line communications systems of practical interest.
