Abstract
In this paper, we focus on point-to-multipoint relaying in cellular system. The base station, the mobile users and fixed relay each have multiple antennas. The special case of MIMO fixed relays with random beamforming is investigated. Via path selection, for any mobile user, only a single relay or the home base station is selected for transmission. Since heavy interference may be cancelled in decoding operation, the relays work in decode-and-forward mode. For simplicity, only two-hop communication is considered. Simulation results show the MIMO relay using random beamforming can improve the capacity performance of cellular system.
