Guaranteed QoS in Dynamic Resource allocation with Adaptive Beamforming for Multiuser Multi-antenna OFDM Systems
In this paper, subcarrier and power allocation problems for multiuser Multi-antenna OFDM systems are investigated. With the goal of minimizing the total transmit power required and guaranteeing each users QoS requirements, a low complexity dynamic resource allocation scheme is proposed. It involves adaptive subcarrier assignment, adaptive power control and beamforming. Mathematical analysises and numerical simulations show that the presented algorithm can exploit multiuser diversity to offer significant system-level performance improvement and guarantee different users QoS requirements effectively.
