Channel Estimation using Antenna Array in Presence of Impulsive Noise

Abstract

The paper deals with the channel estimation using Uniform Linear Array (ULA) antenna. The antennae are treated as individual nodes capable of collecting information and sharing them to the centralized processor for further processing. The environment is assumed to have impulsive noise where the traditional least square methods fail to perform. The paper implements M-type estimator (modified Huber algorithm) to improvise the estimation performance. To demonstrate efficacy of the algorithm, it is implemented with different impulsive noise presence in simulation and compared with traditional method and found to perform better. Moreover the mean stability condition of the algorithm is calculated.
