Abstract :
An efficient algorithm for estimating the time delays and the directions-of-arrival of multiple reflections of a known signal is presented. The algorithm is based on an iterative scheme that transforms the multidimensional maximum likelihood criterion into two sets of simple one dimensional maximisations. Simulation results illustrating the performance of the algorithm in comparison with the Cramer-Rao bound are included
