Abstract:

In this paper, we present simulation and experimental studies of localization and source separation for a bio-complexity bird study based on a new wireless acoustic array node named Voxnet. The Approximate Maximum Likelihood (AML) method is used to estimate blindly the direction-of-arrivals (DOAs) of sources which can be used to both locate the sources using a DOA-based localization method and generate the steering vectors in order to separate the sources via beamforming. Simulation and measured data confirmed the proper operations of the AML-based 2-D/3-D localization and 2-D source separation, as well as the Voxnet hardware nodes.
