Abstract :
In this paper, we presents a MIMO-OFDM based indoor power line communication (PLC) using space-frequency-coding (SFC), space-time-coding (STC), and space-time-frequency-coding (STFC) via low-voltage (LV) indoor power lines. The proposed MIMO-OFDM system model is simulated at the practical PLC fading and impulse noise channels. The used MRC scheme effectively combines both multiple antenna diversity gain and multipath fading diversity gain over 1-phase 3-wire (2×2 MIMO) or 1-phase 2-wire (SISO) power line channels. We analyze and compare SFC, STC, and STFC, with or without crosstalk between antenna paths.
