| 摘 要： | 针对Femtocell网络中干扰管理和功率控制的问题,考虑FBS间的同层干扰,提出基于对数效用的功率控制算法.运用K-Means算法对大量部署的FBS进行分簇,K-Means分簇算法可在低复杂度条件下将FBS划分成不同的簇,以便进行干扰管理.基于对数效用的功率控制算法,能保障FUE处于最低信干噪比,深度优化FBS的发射功率,可在保障吞吐量的同时提升系统能效.

| Abstract: | Aiming at the problem of interference management and power control in Femtocell network,the inter-layer interference among FBS was considered and a power control algorithm based on logarithmic function was proposed.K-Means was adopted for the process of dense FBS clustering in order to expediently manage the inter-layer interference on the condition of the lower complexity.A power control algorithm based on logarithm function model could guarantee the minimum SINR of FUE,deeply optimize the transmission power of the FBS and improve the consumption of system energy while promoting the throughput. |
