Systems and methods for calculating frequency-localized adaptive beamformer weights using weighted overlapping beamform and add techniques applied to adjacent subbands
Systems and methods for calculating frequency-localized adaptive beamformer weights using weighted overlapping beamform and add techniques applied to adjacent subbands
Examples described herein include Weighted Overlap Beamform and Add techniques for calculating frequency-localized weights for adaptive beamformers. Intermediate weights are calculated for overlapping subbands (e.g., using a least-squares solution or a windowed least-squares solution). Each set of intermediate weights may be multiplied by an overlap factor, and combined to provide final weights for a subcarrier.
