摘 要: 为了解决Femtocell中的干扰问题,提出一种基于认知无线电技术、以最大化Femtocell网络中所有Femtocell用户(femtocell user equipement, FUE)的公平性为优化目标的分布式资源分配算法。仿真结果表明:该算法收敛性好,与最大化系统总容量算法相比,系统容量相差很小,但是比最大化系统容量算法和等功率算法更好地保证了系统内同一个Femtocell中所有FUE的公平性,尤其是在FUE的信道质量差别较大时。
关 键 词: 信息科学与系统科学基础学科;Femtocell;分布式;信道分配;功率控制;公平性

Abstract: In order to resolve the problem of interference, a distributed resource allocation algorithm based on cognitive radio technology is proposed which aims to maximize the fairness between all FUEs. Simulation results show that, compared with the algorithm that maximize the system capacity and the algorithm with equal transmitting power, the capacity of our algorithm is only a little smaller than the former and is much bigger than the latter, but our algorithm can fast converge and effectively guarantee the fairness between FUEs.
