提出了一种基于正交频分多址接入系统的混合业务分组调度算法.在调度过程中,对信道状况好的实时业务用户的数据包采用推迟发送的策略.先对缓冲区中累积数据包较多的实时业务用户分配资源,随后对非实时业务用户采用正比公平算法分配剩余的资源.仿真结果表明,提出的算法较好地满足了实时业务的延迟需求,并提高了非实时业务的系统吞吐量. A hybrid service scheduling algorithm based on Orthogonal Frequency Division Multiple Access (OFDM) system is proposed. In the scheduling process, the strategy of delaying the transmission of data packets to real-time service users with good channel conditions is proposed. Real-time business users with more resources are allocated, and then the non-real-time business users are allocated the remaining resources by using the proportional fairness algorithm.The simulation results show that the proposed algorithm can better meet the demand of real-time business delay and improve the non-real-time business System throughput.
