WebMay 18, 2024 · Specifically, the problem of quantized maximum ratio transmission (MRT) beamforming can be interpreted as a Grassmannian line packing problem for both uncorrelated [ 9] and spatially correlated [ 10] Rayleigh fading channels and has been extensively studied. daddy style editingWebGrassmannian line packing. We then consider the correlated channel case, and show that Grassmannian line packing is an artiﬁcial artifact of t he i.i.d. assumption. We show that there are dominant peaks in the eigen-domain when correlation is imposed and the code-book construction should be matched to the correlation in the channel, bins for chest freezer
