Tensor-Based Joint Pitch and DOA Estimation
Yifan Wu, Michael B. Wakin
We propose a tensor-based subspace method for the joint estimation of pitch and direction of arrival (DOA) of multiple harmonic sources. Unlike conventional matrix-based approaches…

Non-uniform Array and Frequency Spacing for Regularization-free Gridless DOA
Yifan Wu, Michael B. Wakin, Peter Gerstoft
Gridless direction-of-arrival (DOA) estimation with multiple frequencies can be applied in acoustics source localization problems. We formulate this as an atomic norm minimization…
