WebMar 15, 2010 · It turns out that, under certain conditions, the DFT is just equally-spaced samples of the DTFT. Suppose is the P-point DFT of . If is nonzero only over the finite … Weban orthogonal DFT-based precoding matrix. 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
