... beamforming vector(s) or righ t unitary matrix of SVD instead of full CSI. Feedback infor- mation in antenna grouping is a beamforming vector (N t ×1 vector) plus additional antenna grouping informa- tion ... is correlated, then the BER performance of antenna grouping degrades. In that case, it is better to use beamforming instead of antenna grouping. In this article,...
