摘　　要：本文主要研究的是在HSDPA无线通信系统中,支持实时业务的分组调度算法。论文对HSDPA通信系统的分组调度算法M_LWDF和EXP算法进行了讨论,并通过视频流业务参考模型对M_LWDF和EXP算法在时延方面进行仿真,来研究它们的时延性能。仿真结果表明,在条件相同的情况下,M_LWDF算法时延略小于EXP算法时延。This paper studies the HSDPA （High Speed Downlink Packet Access） wireless communication system packet scheduling algorithms that supports real -time traflqc. It analyzes detailed M - LWDF and EXP packet scheduling algorithms in HSDPA communication system. And simulations are done to study their time delay performance through video streaming service reference model. The simulation results show M -LWDF algorithms time delay is slightly less than EXP algorithms.
