HomePlug AV system and DLC bit-loading algorithm over OPERA power-line channels with impulsive noise

In this paper, the higher data rate technology of HomePlug, called HomePlug AV, is tested over the power-line channel models proposed by the OPERA project coupled with the Middleton Class A impulsive noise model. In particular, the performance of the recently proposed DLC bit-loading algorithm is analyzed in terms of throughput when different scenarios are considered. Simulations show that the effects of the impulsive noise can be reduced by inserting a clipping module before the OFDM demodulator, thus guaranteeing very promising throughputs even in the worst scenarios.
