Optimal Design of Random Unitary Beamforming for Energy Efficiency in MIMO Broadcast Channels
Random unitary beamforming (RUB) achieves multiuser diversity gain over multiple-input multiple-output broadcast channels with partial channel state information (CSI). RUB can asymptotically achieve the same growth of rate M log log K as the optimal dirty paper coding or sub-optimal zero-forcing bea...
