Abstract
Broadband power-line communication using turbo codes and orthogonal frequency division multiplexing (OFDM) is considered in this paper. It is shown that the performance of conventional turbo coded OFDM systems degrades substantially due to the impulsive noise interference commonly encountered in power-lines. A robust turbo coded OFDM transceiver applying an iterative noise cancellation technique is proposed. Simulation results show that the proposed scheme is robust to impulsive noise while maintaining excellent performance in Gaussian noise.
