摘要：

A new unitary (real-valued) formulation of the popular MODE direction-of-arrival (DOA) estimator is considered. Our unitary MODE algorithm has a reduced computational complexity because it is based on the eigendecomposition of a real-valued covariance matrix. We prove its exact equivalence to the forward-backward MODE (FB-MODE) estimator derived by Stoica and Jansson. This property sheds a new light on the usefulness of FB-MODE. (C) 1999 Academic Press.
