An EM algorithm for direction-of-arrival estimation for narrowband signals in noise

Research output: Contribution to journal › Article › peer-review

Abstract

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.
