Reconstruction of the Samples Corrupted with Impulse Noise in Multicarrier Systems

This paper addresses estimation of the signal samples corrupted with impulse noise in multicarrier systems. The main contribution in our work is application of the well known Bussgang theorem for developing the explicit expression for estimation of the signal samples that are corrupted with impulse noise. In the presented analysis, estimation measure based on minimizing mean square error (MMSE), has been considered. Simulation results show that MMSE measure obtained by the proposed method reduces symbol error rate (SER) for the given number of iterations in comparison with the standard approach without estimation. Simulation results show very good agreement with the results of the theoretic analysis.
