BER analysis of PLC system under Rician channel gain over Nakagami-m additive noise

Power line communication (PLC) deals with the transmission of power as well as data through the use of power lines. It is an emerging field of communication for the home area network of smart grid. The performance of a PLC system is significantly affected by the presence of the additive and multiplicative power line noises. The multiplicative PLC noise results in fading in the received signal strength. This paper provides the performance analysis of a PLC system over Rician fading channel under Nakagami-m distributed additive background noise assuming binary phase shift keying modulation scheme. We derive the probability density function of the decision variable. A numerically computable expression of the analytical average bit error rate of the considered system is obtained. The validity of the derived analytical expressions is closely verified by the simulated results.
