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 user's QoS requirements, a low complexity dynamic resource allocation scheme is proposed. It involves adaptive subcarrier assignment, adaptive power control and beamforming. Mathematical analyses and numerical simulations show that the presented algorithm can exploit multiuser diversity to offer… CONTINUE READING
