Abstract: This paper analyzes the influence of HARQ and PDMA on the PFS algorithm in cdma2000 1xEV-DO Rev A protocol. With setting the threshold of the sensitive users number and employing the PDMA flexibly, this paper proposes an improved PFS algorithm partial to delay-sensitive traffics such as VOIP. Simulation results show that the algorithm enhances the ability of cdma2000 1xEV-DO Rev A protocol in supporting QoS of delay-sensitive traffics such as VOIP.

摘要： 分析cdma2000 1xEV-DO Rev A协议中混合ARQ、包分多址等技术对比例公平调度算法的影响。设置延迟敏感用户数门限并灵活使用PDMA，提出一种偏向延迟敏感业务(如VOIP)的PFS改进算法。仿真结果表明，该算法增强了cdma2000 1xEV-DO Rev A协议对VOIP等延迟敏感业务的QoS支持能力。
