Abstract
We propose a 2-D beamforming system that is designed for multiple source localization, signal enhancement, interference suppression, and noise reduction. The 2-D locations of the sources can be estimated by the wideband MUSIC algorithm. After estimating the locations of the sources, the maximum power beamforming algorithm is applied to enhance the desired signal and attenuate undesired spatially distributed interferences and background noises. Performance gains from simulations and experiments are shown to be promising for multimedia applications.
