Abstract :
In this paper, a scheduling scheme called remote queueing multiple access-code division multiple access (RQMA-CDMA) is proposed. This scheduling scheme provides flexibility in bandwidth allocation and QoS. In addition, admission control guarantees the required Eb/No for multimedia traffic. When comparing the proposed RQMA-CDMA scheme to the existing CDMA-GPS, the results show an improvement in system performance in terms of dropped packets, delay and increased operational throughputs.
