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

Gridless Underdetermined DOA Estimation for Mobile Agents with Limited Snapshots Based on Deep Convolutional Generative Adversarial Network

Remote Sensing
Deep learning techniques have made certain breakthroughs in direction-of-arrival (DOA) estimation in recent years. However, most of the current deep-learning-based DOA estimation methods view the direction finding problem as a grid-based multi-label ...

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.

Robust Beamforming and DOA Estimation

, 2012
The traditional approach to the design of adaptive beamformers assumes that the desired signal components are not present in training data, and the robustness of beamformer is known to depend essentially on the availability of signal-free training data.
