An EM Algorithm For Direction-Of-Arrival Estimation For Narrowband Signals In Noiset
Michael I. Miller, Daniel R. Fuhrmann · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1988
We derive a generalized EM algorithm for the maximum-likelihood estimation of the directions-of-arrival of multiple narrowband signals in noise, and prove that all of the limit points of the algorithm are stable and satisfy the neces-sary maximizer conditions. The deterministic signal model is considered here in which estimates of the unknown signal amplitudes are generated.
