Abstract
Apparatuses, methods and systems for beamforming are disclosed. One embodiment of a method includes generating a beamforming matrix, including obtaining a channel matrix of a multiple-input, multiple-output (MIMO) between a multiple antenna transmitter and a receiver, determining an initial beamforming matrix based on a singular value decomposition of the channel matrix, generating a final beamforming matrix comprising re-ordering columns of the initial beamforming matrix for at least one sub-carrier of a multi-carrier signal based on a signal characteristic, processing a plurality of multi-carrier signals using the final beamforming matrix, and transmitting the processed plurality of multi-carrier signals through a plurality of transmit chains.
