摘要
1xEV-DO技术是旨在前、反相链路提供高速不对称性分组数据速率。本文结合1xEV-DO的链路结构特点,提出一种基于影子价格策略[1]的按比例公平规则。该算法比传统的比例公平规则在抗信号快变上取得了改进,提高了系统的总体性能。并在仿真中对流量价格引入延迟分量[2],进一步改善了系统的延迟特性。
xEV-DO provides asymmetric data rates on the forward and reverse links, and is optimized for packet data services. A PROP-FAIR rule based on shadow price, for which the structure of the 1xEV-DO link is considered, is proposed for 1xEV-DO. It can do better in suppressing drastical variation of channel quality. In simulation part, We also suggest a modified flow price with delay factor to make a further progress in delay performance for 1xEV-DO system.
