Robust time delay estimation based on non-Gaussian impulsive acoustic channel

Abstract

The aim of this letter is to propose a new robust method for source localization over impulsive noise and investigate its practical implications. The method uses a non-linear data transformation associated with the generalized cross-correlation technique. Hence, simulations and experiments show better performance than traditional methods without increasing the computational cost. Our practical experiments indicate the possibility of obtaining a correlated impulsive noise, in which the proposed method is still presenting accurate estimations.
