Abstract:
In a method for generating steering matrices for beamforming, one or more subsets of one or more maximum transmit steering matrices are selected, where the maximum transmit steering matrices correspond to a maximum number of spatial streams able to be transmitted from a transmitter to a receiver. The subsets correspond to an actual number of spatial streams to be transmitted, and the subsets are applied to spatial streams to be transmitted. In an apparatus for generating steering matrices, a steering matrix calculator is configured to determine, from maximum transmit steering matrices, a plurality of steering coefficients corresponding to an actual number of spatial streams.
