摘要
本文分析讨论了导频发射功率对能量效率的影响,以天线数目、导频功率和数据功率作为待优化变量的能效函数,采用交替优化来得到最大值。针对天线数目优化,运用LambertW函数推导出最优天线数目的闭式表达式,然后采用黄金分割法交替迭代目标函数。
The influence of pilot transmission power on energy efficiency is analyzed and discussed.The number of antennas,pilot power and data power are taken as the energy rate function of the variables to be optimized,and the maximum value is obtained by alternating optimization.In order to optimize the number of antennas,the closed-form expression of the optimal number of antennas is derived by using the LambertW function.Then the golden section method is used to alternately iterate the objective function.
