Abstract
We present an efficient algorithm for estimating the time delays and the directions-of-arrival (DOAs) of multiple reflections of a known signal. The algorithm is based on an iterative scheme that transforms the multidimensional maximum likelihood criterion into two sets of simple one-dimensional (1-D) maximization problems. Simulation results illustrating the performance of the algorithm in comparison with the Cramer-Rao bound are includedKeywords
