Abstract

OFDM Orthogonal Frequency Division Multiplexing is a multicarrier modulation scheme. It is widely used in wired and wireless communication systems. Impulse noise can be mitigated by considering it as a sparse signal in time, and using recently developed algorithms for sparse signal reconstruction. We propose an algorithm that utilizes the guard band null subcarriers for the impulse noise estimation and cancellation.
