Narrow-band interference model for OFDM systems for powerline communications

A narrow-band interference (NBI) model for the powerline communications channel is presented. We give frequency domain details and analysis of the NBI model specifically for OFDM systems; it can easily be adapted to model NBI for other communications systems. We also show that by making the same assumptions as in the Middleton class A model, our NBI model becomes the Middleton Class A noise model.
