A Review of Bit Allocation for MCM Techniques in Power Line Communication for Smart Grids

چکیده
In recent history there has been an enormous development in the subject area of Power Line Communications (PLC), since it has become possible due to advanced digital communications and digital signal processing techniques to use power lines for data transmission. PLC allows the use of the dynamic and far-reaching power cables to support high speed communication capabilities. Discrete Multi-tone (DMT) is a form of multicarrier modulation (MCM), particularly suited to wire line communications, therefore it is more suitable modulation technique for PLC systems. In this paper, we present an overview of various bit loading algorithms that are proposed in literature, of a DMT system for smart grid applications using PLC. For the PLC transceivers, we consider DMT modulation based on an adaptive bit loading technique of the subcarriers. We have also compared two basic rate adaptive bit loading algorithms, Water-filling and Levin Campello, for PLC in Smart Grid communication applications.
