Decoupled Direction-of-Arrival Estimations Using Relative Harmonic Coefficients
TL;DR: In this article, a decoupled source direction-of-arrival (DOA) estimation algorithm using relative harmonic coefficients (RHC) is proposed. But the proposed algorithm requires the source's elevation and azimuth to be estimated separately.

TL;DR: The theory of WFS with PSC is revised with respect to other derivations, extended for the application to focus points, and validated by numerical simulation.

Microphone array position calibration in the frequency domain using a single unknown source
TL;DR: Numerical results indicate that this algorithm converges to the right solution, and therefore that using frequency measurements for position calibration is a valid concept for dense arrays, as an alternative to time-domain methods in reverberant domains.

Sketching for Nearfield Acoustic Imaging of Heavy-Tailed Sources
TL;DR: A heavy-tail \(\alpha \)-stable probabilistic model for acoustic source localization with known but arbitrary geometry of the microphone array that compares favorably with state of the art for localization in realistic simulations of reverberant environments.
