Application of multiple input multiple output power line communication (MIMO-PLC) to power systems

Abstract

Multiple input multiple output power line communication is presented with its major characteristics and models. Orthogonal frequency division multiplexing modulation scheme applied to power line channel model is presented, also, combination of orthogonal frequency division multiplexing with MIMO Alamouti space time block codes to improve reliability and data rate performance of the system is done. The evaluation of the orthogonal frequency division multiplexing-PLC system over power line communication channel is performed. The comparison between simple PLC and MIMO-PLC systems based upon achieved data rates and reliability in terms of bit error rate is presented
