摘要
研究了宽带正交频分复用多址(OFDMA)系统中存在多种不同业务时的无线资源管理问题,给出了多业务情况下基于效用公平的公平调度算法.仿真结果表明,基于效用公平的算法,可以保证各用户间的吞吐量符合比例公平原则,并能明显增加系统总吞吐量.
This paper studied some aspects of radio resource management for orthogonal frequency division multiplexing multiple access (OFDMA) systems with multimedia services supported, and presented an opportunistic fair scheduling algorithm of multimedia services. The algorithm is based on utilitarian fairness (UF). The simulation results show that the UF based algorithm can guarantee the proportional fairness of the throughput between every users, and evidently increase the total throughput of the system.
