In accordance with one method, indications of channel matrices for a plurality of receivers are obtained. Further, a beamformer matrix is formulated as a linear combination of columns of hermitians of the channel matrices. In addition, coefficients of the hermitians in the linear combination are determined to compute the beamformer matrix such that a lowest reception rate among reception rates of each of the receivers is maximized. Data signals are transmitted to the receivers by applying the computed beamformer matrix to data symbols to maximize the lowest reception rate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Link layer multicasting systems and methods","description":"Beamforming systems and methods are disclosed.
