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.
