Abstract:Beamforming (BF) is an effective method to restrain interference in cellular communication systems. Steering beam direction in 3D space can improve useful signal power that user equipments (UEs) received and eliminate interference effectively. In this paper, we focus on how to choose 3D-BF angles of beam and propose a cooperative angle selecting scheme based on maximum signal to leakage plus noise ratio (SLNR) (CAS-MSLNR) to increase sum throughput of Heterogeneous Network (HetNet). In the proposed scheme, 3D-… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
