A method for beamforming in a wireless communication begins by receiving a baseband signal. The method continues by receiving a feedback signal that includes a subset of angles, wherein a set of angles provide polar coordinates for a unitary matrix and wherein the subset of angles is a subset of the set of angles. The method continues by determining at least one remaining angle of the set of angles based on the subset of angles. The method continues by determining the polar coordinates for the unitary matrix. The method continues by digitally beamforming the baseband signal using the unitary matrix.
