  • Abstract
    Optimal transmitter beamforming with per-antenna power constraints has been a long outstanding problem. In this paper, we derive the necessary and sufficient conditions for optimal single-stream and multi-stream transmitter beamforming with per-antenna power constraints. We also develop iterative algorithms for single-stream and multi-stream transmitter beamforming, and prove the algorithms converge to the optimal solutions.
