  It is well known that asynchronous impulsive noise is the main source of
distortion that drastically affects the power-line communications (PLC)
performance. Recently, more realistic models have been proposed in the
literature which better fit the physical properties of real impulsive noise. In
this paper, we consider a pulse train model and propose a thorough analysis of
the impact of impulsive noise parameters, namely impulse width and amplitude as
well as inter-arrival time, on the bit error rate (BER) performance of
orthogonal frequency division multiplexing (OFDM) broadband PLC. A comparison
with the conventional Bernoulli-Gaussian (BG) impulsive noise model exhibits
the difference between the two approaches, showing the necessity of more
realistic models.
