A simple Normalized Least Mean Square Algorithm Robust to Impulse Noise

This paper suggests a simple impulse noise detection normalized least-mean-square (NLMS) algorithm as an effective adaptive algorithm against impulsive noises. Initially, to have a fast algorithm, an optimization problem is introduced and then an oracle NLMS algorithm is devised. To have a practical variant of oracle NLMS algorithm, a simple impulse noise detection NLMS algorithm is proposed. The simulation results show the effectiveness of the suggested algorithm in terms of convergence rate and complexity
