在本文中，我们提出了两个修改的比例公平调度算法的多用户多载波系统。与现有的比例公平调度算法相比，我们提出的算法被设计为支持实时应用的延迟约束，以及保证一定程度的公平性。仿真结果表明，所提出的调度算法不仅能以较低的复杂度基本实现比例公平，而且能支持实时业务用户。
In this paper, we propose two modified proportional fair scheduling algorithms for multiuser multicarrier systems. Compared to the existing proportional fair scheduling algorithms, our proposed algorithms are devised to support the delay constraint for the real-time applications as well as to guarantee a certain level of fairness. The simulation results show that the proposed scheduling algorithms not only almost achieve proportional fairness with low complexity but also support real-time service users.
