  • Abstract
    In this paper a new bit-loading algorithm for the OFDM-based turbo coded HomePlug AV system is proposed. To better exploit the error correction capabilities of the turbo code, this algorithm tries to maximize the throughput while guaranteeing a target BER over a set of sub-carriers using a new metric based on the LLRs. The performance of the considered system, in terms of throughput and BER, is evaluated, using a realistic power-line channel model. Furthermore, data- aided channel and SNR estimates are investigated and their performance compared with the ideal case.
