Abstract
The performance of Power Line Communication
(PLC) degrades due to the presence of different types of noise
interferences generated by electrical appliances. This paper
investigates the bit-error rate (BER) performance of a higherorder
64-QAM constellation with orthogonal frequency
multiplexing modulation (OFDM) in presence of impulsive noise
modelled as Middleton Class A over a multipath PLC. It is
observed that BER for the impulsive noise is higher than the
background noise. The BER further deteriorates on increasing the
level of the impulsive noise, even while being injected into the PLC
channel at a lower rate. Investigations would assist applying
methods to mitigate and reduce the effect of impulsive noise over
PLC systems for higher constellations with a view to increase the
data rates
