      Abstract
      A tree structured Expectation Maximization (EM) algorithm is proposed and applied to the wide-band angle of arrival estimation. It may be seen as a generalization on EM using the ideas of Cascade EM algorithm and Space Alternating Generalized EM algorithm. Also, for passive data acquisition, robust and efficient alternatives for the estimation of the source signals are investigated.
