【摘要】 在对无线资源分配和下行链路分组数据调度算法研究的基础上,提出了一种适应于自适应OFDMA系统的联合算法,即K&H/MPF算法。理论分析和仿真结果表明:该算法在满足不同用户QoS要求的前提下,不但能够提供比多载波正比公平调度器更高的容量增益,而且以极大的灵活性实现了用户数据的公平发送。更多还原

【Abstract】 Based on the study on the radio resource allocation and downlink packet data scheduling algorithms,their joint scheme,K&H/MPF,is proposed,which is expected to be applied to adaptive OFDMA systems supporting multiple QoS classes.The results demonstrate that K&H/MPF not only provides for user fairness with explicit QoS guarantees and flexible parameters setting,but also achieves the higher system throughput compared with multi-carrier proportional fair(MPF) scheduler.更多还原
