Abstract:

The energy efficiency (EE) optimization in uplink multi-user single-input multiple-output systems was addressed. The EE optimization model with minimum data rate requirement was first proposed, and the feasibility of model was analyzed. Then a convex approximation and geometric programming based energy-efficient joint beamforming and power control algorithm was developed. The convergence of the algorithm was proved. Simulation shows that the proposed algorithm can significantly improve EE performance and meet data rate requirements.

Key words: multi-user single-input multiple-output, uplink, energy efficiency, beamforming, power control
