天线下倾角对于网络能量效率有着重要影响。提出了一种基于黄金分割搜索的针对能效的天线下倾角自优化算法，算法分为3个部分：根据黄金分割搜索原理确定搜索区间；通过数值搜索快速收敛到最优解附近；通过对天线下倾角进行小步长的微调逼近最优下倾角。仿真结果表明：算法能够有效快速地搜索到能效最优的下倾角，并具有针对网络环境变化的自修复能力。

The antenna tilt has a strong impact on the energy efficiency of a cellular network.This paper introduces an algorithm based on the golden section search(GSS)for self-optimisation of antenna tilt.The proposed method consists of three phases:first,confirm the search range by using the GSS method;second,quickly converge to a near optimal quantity;third,approach the optimal value with fine tuning of down-titl angle in a small step.The proposed algorithm has self-healing capabilities to cope with the environment changes. The simulation results verify the practicability and the self-healing capabilities of the proposed algorithm at last.
