摘要:

针对上行多用户单入多出系统的能量效率优化问题,建立了最小速率限制下的能量效率优化模型,分析了模型的可行性条件。基于凸逼近和几何规划设计了一种高能效的联合波束赋型与功率控制算法。理论分析证明了算法能快速收敛。仿真结果表明,算法在保证最小速率需求的同时能显著提高能量效率。

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
