| 摘 要： | 针对OFDM系统下行链路,无线分组调度须实现系统吞吐量、多业务QoS带宽速率、时延保证和公平性方面的诸多要求,提出一种能够实现自适应补偿的累积服务时延比例公平调度(DCPF)算法.该算法根据信道状态、累积服务时延等进行多目标判决,实施无线分组调度.分析和仿真结果表明,该算法可提供较好的QoS时延保证,并极大地提高各用户长期公平性.

| Abstract: | Wireless resource scheduling algorithm in beyond 3rd generation mobile communication system needs to implement high system throughput,satisfy QoS demand in both data rate and delay,also perform well in subscriber fairness.This paper proposed a delay cumulated proportional fair(DCPF)algorithm with property of adaptive compensation.This algorithm makes packet scheduling judgment on the basis of channel condition and cumulated service delay.The theoretic analysis and computer simulation results show that this algorithm can provide well QoS characteristic,and enhance long-term fairness greatly. |
