Abstract:
We present multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) based broadband power line communication (BPLC) using antenna and fading diversity. We evaluate the proposed MIMO-OFDM system over multi-conductor power line channels, with or without cross-talk between the antenna paths. The proposed scheme employs maximum ratio combining (MRC) that effectively combines both the multiple antenna diversity gain and the multipath fading diversity gain over 3-phase (2x2 MIMO, outdoor) power line channels. Simulation results prove that the proposed scheme improves the bit error rate performance over the existing schemes, irrespective of whether cross-talk exists.
