Abstract

This paper proposes a design of multi-user beamformer under a per-antenna power constraint (PAPC). The proposed beamforming method effectively utilizes the antenna power and maximizes the beamforming gain while suppressing the inter-user interference. The resulting high beamforming gain and low interference can lead to the high sum-rate. All the processes of proposed beamforming method demand only linear operations, and this guarantees the low computational complexity. The simulation results show that the proposed method can provide the high sum-rate with significantly less computational complexity compared to existing beamforming methods that use complex optimization solvers to satisfy the PAPC.
