摘要
提出一种有效降低小蜂窝间同层干扰的算法。首先依据干扰关系通过对各小蜂窝进行分簇来降低算法的复杂度,提高系统的频谱效率;随后提出一种基于后悔值的博弈算法(RBGA)来对各小蜂窝簇进行频谱分配,通过避免有强烈干扰的小蜂窝间分配相同的频谱来避免同层干扰。仿真结果表明,所提算法能有效提高系统的性能。
This paper proposes an efficient interference avoidance algorithm to decrease the co-tier interference between small Ceils. Firstly, according to the interfe^nce relationship between small cells, the algorithm divides them into clusters so as to decrease the complexity of algorithm and increase the system spectrum efficiency. Then, a regret value-based game algorithm is proposed to allocate spectrum for clusters. This can avoid co-tier interference hetween small ceils though allocating different spectrums to interfered small cells. Simulation results show that the proposed algorithm can improve system performance efficiently.
