Novel methods are presented which estimate the direction of arrival (DOA) of coherent
signals by efficiently exploiting forward and backward vectors. Some correlation vectors or …

A new method is proposed for direction-of-arrival estimation of coherent signals in the
presence of correlated noise fields. The method comprises two steps: a first step for …

In this paper, we propose a modified symmetric sensor array for the estimation of
uncorrelated and coherent sources by reconstructing the modified Toeplitz matrices. The …

This letter offers several new insights into the maximum-likelihood direction-of-arrival (DOA)
estimation problem, when the number of sources exceeds the number of sensors. Two …
