Now-a-days Power Line Communications have been the subject of an important research work. Power line communication is an attractive alternative choice for traditional networks due to its ability to offer broadband internet access, cable television telephone service and home automation. At the same time, the growing demand for multimedia communications provides a good prospect for PLC as a promising transmission technique. However, power line communication transmission affected from many problems such as interference, multipath noise attenuation delays, presence of echoes, frequency selective fading due to multipath etc. So it create a need to employ a suitable modulation scheme such as Orthogonal Frequency Division Multiplexing (OFDM) to counter its unwanted effects on signal transmission.
