与分布式天线系统中传统的功率分配方案不同,本文提出了一种以低复杂度最大化能量效率(EE)为目标的新型功率分配算法。优化过程分为两步,第一步是找到任意固定总动态功率约束对应的最佳天线数量。第二步是选择信号衰减最大的最佳天线。与传统的EE最大化功率分配方法相比,在保持EE性能的同时,计算复杂度大大降低。仿真结果证实,与穷举搜索相比,所提出的低复杂度算法几乎没有性能下降。
Different from traditional power allocation schemes in distributed antenna systems, a novel power allocation algorithm aiming at maximizing energy efficiency (EE) with low-complexity is presented in this letter. The optimization process is divided into two steps, the first step is to find the optimal number of antennas corresponding to any fixed total dynamic power constraints. The second step is to select the optimal antenna with the greatest signal attenuation. Compared with traditional EE maximization power allocation methods, the computation complexity is greatly reduced while the EE performance is maintained. Simulation results confirm that the proposed low-complexity algorithm has barely performance degradation compared with exhaustive search.
