Direction of arrival estimation using the rotating equatorial microphone

Frontiers in Signal Processing
Introduction: Direction of arrival (DOA) estimation of sound sources is an essential task of sound field analysis which typically requires two or more microphones. In this study, we present an algorithm that allows for DOA estimation using the previously

Generalized Framework to Subspace-Based DOA Estimation

IEEE Transactions on Signal Processing
A generalized framework to subspace-based direction-of-arrival (DOA) estimation in the presence of unknown noise field and other imperfections is proposed. Provided the noise covariance matrix estimate, a forward-only and its forward-backward extension rooting-based DOA estimator is developed.
