Abstract :
In this paper, we consider the group oriented beamforming taking into account the quality of service (QoS) requirement for multimedia applications in multiuser/multi-rate OFDM system. The aim of this paper is to find the scheme for maximizing the system throughput while guarantee the QoS requirements and fairness for all services. The simulation result indicates that this scheme proposed in this paper has a higher improvement for the system performance and power utilization regarding to BER and throughput.
