Abstract :
This paper addresses the problem of time delay estimation in spatially correlated noises. We assume that the signals are non-Gaussian and the noises are Gaussian. Two new classes of criteria based on higher order cumulants are established, from which new algorithms for time delay estimation are proposed. Simulation examples are given to demonstrate the effectiveness of the new algorithms
