Moreover, we demonstrate that for UL-AEs - provided that the channel is spatially correlated - the beamforming weight-vectors in a DFT-based codebook approximately match the distribution of the optimal beamforming weight-vectors. As a result, the DFT-based codebook is indeed effective. However, we will
