Coordinated downlink beamforming in multicell wireless network
Communications and Electronics（2014）
摘要
We consider the joint design of downlink beamforming vectors in a multicell multi-antenna wireless network to maximise the network sum rate subject to base station power and quality-of-service (QoS) constraints. It is shown that the problem is reformulated by a concave program, for which an efficient iterative procedure of low complexity is then developed.
