Power line communication system modeling based on coded OFDM

Over the last years there is more intensive research on realization of PLC (Powerline Communication) as access network. Since the power line channel shows hostile properties for communication signal transmission (noise, multhipath, strong channel selectivity), the major issue is to choose an adequate modulation technique for the evolution and realization of such a system. This paper introduces a power line communication system model based on the coded OFDM (Orthogonal Frequency Division Multiplexing) modulation technique. Coded OFDM presents a good performance in difficult signal transmission environments and stands as a good candidate for the realization of a PLC system.
