An Optimal Power Allocation Scheme in Downlink Multi-user NOMA Beamforming System with Imperfect CSI

In this paper, we consider downlink multi-user non-orthogonal multiple access beamforming system with imperfect channel state information. In this system, we employ regularized zero-forcing precoding to reduce inter-cluster interference since it has a good performance-complexity balance. By maximizi...
