中文摘要：
针对多天线广播下行链路通信系统，研究了一种鲁棒能效联合波束成形和功率分配算法。首先，鲁棒能效优化问题描述为满足一定功率约束的系统和速率与系统消耗之比的最大化优化问题。其次，利用分数规划理论及用户速率与最小均方误差之间的关系，把所描述的分数规划优化问题转化成参数化多项式优化问题。然后，利用拉格朗日对偶及单调优化理论，提出了一种有效的鲁棒能效优化算法。数值仿真结果表明，相对于传统的非鲁棒能效优化算法，所提鲁棒能效优化算法可获得明显的能效性能增益。
英文摘要：
A robust energy efficient joint beamforming and power allocation algorithm is studied for multiple antennas broadcast downlink communication system.The robust energy efficient optimization problem is first formulated as the maxi-mization of the ratio between the system sum rate and the system power consumption subject to a predefined power con-straint.The considered fractional programming optimization problem is then transformed into a parameterized polynomial form optimization problem via using the fractional programming theorem and the relation between the user rate and the mini-mum mean square errors （MMSE）.Final,an effective robust energy efficient optimization algorithm is proposed by exploi-ting the Lagrangian duality theorem and monotonic optimization theorem.Compared to the classical non-robust energy effi-cient optimization algorithm,the proposed algorithm can obtain an obvious energy efficiency performance gain.
