Abstract
We present MIMO-OFDM based broadband power line communication (BPLC) that uses antenna and fading diversity. We evaluate the proposed MIMO-OFDM over BPLC channels, with or without cross-talk between antenna paths. The proposed scheme employs maximum ratio combining (MRC) that effectively combines both multiple antenna diversity gain and multipath fading diversity gain over 3-phase (2×2 MIMO, outdoor) or 1-phase (SISO, indoor) power line channels. Simulation results prove the performance advantage of the proposed scheme, whether or not cross-talk exists, over existing schemes.
