Abstract:
This paper presents a MIMO-OFDM based power line communication (PLC) system using space-frequency coding (SFC), space-time coding (STC), and space-time-frequency coding (STFC) over statistical indoor power line channels. We present a maximum ratio combining (MRC) scheme that provides both multiple antenna diversity gain and multipath fading diversity gain. By simulation, we verify that the proposed MRC is effective to both 2x2 MIMO and SISO over indoor power line channels. On the simulation, we consider both perfect and imperfect channel estimation. We also simulate SFC, STC, and STFC over power line channels, with or without crosstalk between antenna paths; STFC and STC are more robust to crosstalk than SFC; STFC with some added complexity overpowers the other coding schemes in terms of bit-error rate performance. Further, STFC is less sensitive to impulse noise index A than STC and SFC.
