摘要
针对三维多输入多输出（3D MIMO）正交频分多址（OFDMA）系统，提出了一种能效优化算法。该算法在垂直波束成形技术下，以能量效率最大化为目标，通过调整资源分配、功率分配、天线的波束下倾角来提高系统能量效率。根据分数优化理论，将复杂的分数优化问题转化为较易求解的整式优化问题，然后引入拉格朗日乘子通过不断迭代得到能量效率的最优值。仿真结果表明，所提算法在较少迭代次数下可以获得更高的能量效率。
Abstract
An energy-efficient optimization algorithm was proposed for the 3D MIMO-OFDMA communication system.The proposed algorithm based on vertical beamforming technology maximized energy efficiency by adjusting the resource allocation
power allocation and the downtitles of the beam.According to the theory of fractional optimization
the complex fractional optimization problem could be converted into a more tractable integral optimization problem.The lagrangian operator was introduced to obtain the optimal value of energy efficiency by iteration.Simulation results show that the proposed algorithm can achieve higher energy efficiency with fewer iterations.
