Localization of acoustic sources using miniature microphone arrays poses a significant challenge due to fundame ntal limitations imposed by the physics of sound propagation. Wi th sub-wavelength distances between the microphones, resolv ing acute localization cues become difficult due to precision ar tifacts. In this paper we propose a framework which overcomes this limitation by integrating signal-measurement (analog-to-digital conversion) with statistical learning (bearing estimation). At the… CONTINUE READING
