Abstract :
We present a MIMO-OFDM based broadband power line communication (BPLC) with maximum ratio combining. We evaluate the proposed MIMO-OFDM over BPLC channels, with or without cross-talk between antenna paths. The suggested maximum ratio combining (MRC) scheme effectively combines both multiple antenna diversity gain and multipath fading diversity gain over 3-phase (2×2 MIMO, outdoor) or single-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.
