Abstract
Examples described herein include recursive techniques for calculating frequency-localized weights for adaptive beamformers. Components of solutions for other subcarriers are weighted and used to calculate weights for a particular subcarrier. For example, a previously-calculated cross-correlation vector and/or inverse covariance matrix from another subcarrier may be updated for use in calculating weights for a subsequent subcarrier. In some examples, the previously-calculated components are weighted by a forgetting factor. The previously-calculated components themselves may have weighted contributions from yet previously-calculated components.
