Joint DOA and Multi-Pitch Estimation Using Block Sparsity

Kronvall, Ted LU ; Adalbjörnsson, Stefan Ingi LU and Jakobsson, Andreas LU orcid (2014) 2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP 2014) p.3958-3962
Abstract
In this paper, we propose a novel method to estimate the fundamental frequencies and directions-of-arrival (DOA) of multi-pitch signals impinging on a sensor array. Formulating the estimation as a group sparse convex optimization problem, we use the alternating direction of multipliers method (ADMM) to estimate both temporal and spatial correlation of the array signal. By first jointly estimating both fundamental frequencies and time-of-arrivals (TOAs) for each sensor and sound source, we then form a non-linear least squares estimate to obtain the DOAs. Numerical simulations indcate the preferable performance of the proposed estimator as compared to current state-of-the-art methods.
