一种Femtocell网络中的分布式下行资源分配算法

In order to improve the capacity of traditional cellular networks and to improve the quality of indoor coverage, Femtocell was proposed into the traditional cellular networks. It covers a small range and transmits with small power.The application of Femtocell brought a lot of interference problems, and effective resource allocation algorithms are very important to solve these problems.In this paper, a distributed resource allocation algorithm based on cognitive radio technology is proposed which aims to maximize the fairness between all FUEs, including channel allocation and power control. 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 convergent and effectively guarantee the fairness between FUEs.
