femtocell双层网络中基于分簇的资源分配
发布时间：2019-08-19 14:18
【摘要】：针对异构网络中毫微微小区(femtocell)之间的同层干扰和femtocell与宏小区(macrocell)之间的跨层干扰,提出一种基于分簇的资源管理方案。该方案包括两部分:第1部分是宏基站(macrocell base station,MBS)利用三轮子信道分配算法为宏用户分配子信道,再采用注水算法分配功率;第2部分首先采用遗传模拟退火算法为femtocell分簇,再利用启发式算法和卡罗需-库恩-塔克(Karush-Kuhn-Tucker,KKT)条件为毫微微用户分别分配子信道和功率。仿真结果表明,该方案有效地抑制了网络中的这两种干扰,满足了用户的数据速率需求,有效地提高了频谱效率。
[Abstract]:Aiming at the same layer interference between (femtocell) and (macrocell) in heterogeneous networks, a resource management scheme based on clustering is proposed. The scheme consists of two parts: the first part is the macro base station (macrocell base station,MBS) uses the three-wheel channel allocation algorithm to allocate the subchannel to the macro user, and then uses the water injection algorithm to allocate the power; in the second part, the genetic simulated annealing algorithm is used to cluster the femtocell, and then the heuristic algorithm and Carol Kuhn-Tucker (Karush-Kuhn-Tucker,KKT) condition are used to allocate the subchannel and power respectively. The simulation results show that the scheme effectively suppresses these two kinds of interference in the network, meets the data rate requirements of users, and effectively improves the spectral efficiency.
