An Optimal Interleaving Scheme With Maximum Time-Frequency Diversity for PLC Systems

In this paper, an optimal interleaving scheme with maximum time-frequency diversity is proposed to combat against the narrowband interference (NBI) and time-domain impulsive noise for orthogonal frequency-division multiplexing (OFDM) systems in power-line communications (PLC). To improve the anti-NBI and anti-TIN performance, we propose two criteria based on which the optimized interleaving scheme is designed: 1) to increase the number of different OFDM blocks for one forward error correction (FEC) codeword, which is aimed at TIN mitigation and 2) to increase the number of different subcarriers mapped to the data symbols in one FEC codeword, which is aimed at NBI mitigation. Simulations show that the proposed interleaving scheme can effectively reduce the impairments caused by NBI and/or TIN in OFDM systems under PLC environments and, hence, achieve better performance than the conventional block interleaving scheme.
