Clustered Random Beamforming and Hierarchical Modulation for Large Multi-User MIMO Downlinks

Clustered Random Beamforming and Hierarchical Modulation for Large Multi-User MIMO Downlinks

<p dir="ltr">We propose a novel clustered random beamforming (RBF) scheme for multi-user multiple-input multiple-output (MIMO) downlink systems. The objective of this scheme is to maximize the number of served users while ensuring that each user meets a minimum quality of service (Qo...
