摘要翻译：
提出了一种大规模多输入多输出(MIMO)系统中能量有效的分布式最坏情况鲁棒功率分配方法。我们假设信道状态信息(CSI)误差有界，所有信道都位于某个有界不确定性区域。将该问题表示为具有无穷大约束的极大极小问题。首先用三角形和Cauchy-Schwarz不等式求解内问题，然后利用分式规划和逐次凸逼近(SCA)技术将问题转化为凸优化问题。最后通过分配方式得到闭合形式的发射功率。仿真结果验证了算法的收敛性和功率分配的鲁棒性。给出了仿真结果中能量效率最大的发射天线数目。

英文摘要：
  This letter proposes an energy efficient distributed worst case robust power allocation in massive multiple input multiple output (MIMO) system. We assume a bounded channel state information (CSI) error and all channels lie in some bounded uncertainty region. The problem is formulated as max-min one with infinite constraint. At first, we solve the inner problem with triangle and Cauchy-Schwarz inequality, then by fractional programming and successive convex approximation (SCA) technique problem transfers to a convex optimization. Finally closed form transmit power is obtained with distribution way. Simulation results demonstrate proposed algorithm convergence and validate robust power allocation. Also, the appropriate number of transmit antenna to have maximum energy efficiency in simulation result is shown.
