Abstract

Multiple Input Multiple Output (MIMO) methods significantly improve the coverage of Power Line Communications (PLC) compared to Single Input Single Output (SISO) systems. This paper describes the implementation and results of the first real-time MIMO PLC feasibility study. Our system setup includes two PCs, each containing two FPGAs. It enables the comparison of SISO versus MIMO PLC transmissions regarding parameters such as data throughput, BER, channel estimation, QAM constellations, equalizer matrices, etc. Additionally Beamforming may be applied on the fly. Field tests in private homes show the significantly increased data throughput and link reliability of the MIMO PLC system.
