ABSTRACT

In recent years, Smart Grid has received widespread attention from both academia and industrial communities. As the basis for its implementation, multiple communication technologies will be employed. However, power line communication (PLC) can present a more extensive and pervasive solution [2]. Up to now, narrow-band (NB) (3–500 kHz) and broad-band (BB) (2–100 MHz) PLC have been developed progressively [3,4]. Especially in the last half decade, multi-carrier NB PLC with a relatively high data rate ranging from 10 to 500 kbps has emerged and aroused immense industry interest as it is considered to be suitable for a part of the Smart Grid applications.
