OFDMA系统中资源公平调度算法研究

A Study on Resource Fairness Scheduling Algorithms for the OFDMA Systems

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公平调度问题,深入分析了经典的资源调度算法——用户最小容量最大化算法,提出了一种明显改善公平性能的改进算法,仿真结果证明,改进算法在各种应用环境下,都具有良好的公平性能,能为不同业务类型的用户提供较严格的速率保证。

The paper studied the radio resource fairness scheduling for Orthogonal Frequency Division Multiplexing Multiple Access （OFDMA） systems which was supporting several different services. After deeply analyzing a classical resource scheduling algorithm,which maximize the worst user＇s capacity, an improved algorithm which can evidently enhance the fairness performance was proposed. Simulation results show that the improved algorithm can keep a better fairness performance under different application environment, and can more strictly guarantee the required data rate for different service.
