摘要：
The expectation maximization (EM) algorithm is presented for the case of estimating direction of arrivals of unknown deterministic wideband signals, Alternative regularized least squares estimation techniques for the required signal estimation and a tree structure for the data mapping in the Ehl algorithm are proposed. Extensive simulation results are presented for comparison of the proposed algorithms with the conventional EM approach and the current high-resolution methods of wideband direction finding.
