A RELAXATION ALGORITHM FOR DECENTRALIZED RESOURCE ALLOCATION IN FEMTOCELL NETWORKS

摘要：

　　Dynamic spectrum sharing can improve the spectrum efficiency under some constraints on the interference to the authorized users.However,in femtocell networks the sensing reliability of femtocell access point (FAP) is limited by the channel fading and device preference.In this paper,we consider the influence of miss detection and false alarm to the macrocell user (MU) and model this problem as a joint optimization of spectrum detection and power allocation.A relaxation algorithm for decentralized resource allocation has been proposed to maximize the throughput of the femtocell networks.The simulation results demonstrate that the proposed algorithm can improve the throughput of femtocell networks than uniform threshold algorithm.
