摘要
主要研究了HSDPA无线通信系统中的分组调度算法。对HSDPA通信系统的分组调度算法M-LWDF和EXP进行了分类讨论,并通过视频业务参考模型对M-LWDF和EXP算法在丢包率方面进行仿真来研究它们的性能。仿真结果表明,在条件相同的情况下,M-LWDF算法比EXP算法的丢包率略高。
Packet scheduling algorithms in HSDPA wireless communication system were researched in this paper. M-LWDF and EXP packet scheduling algorithms in HSDPA system were discussed and their performances were simulated according to packet loss rate using video trafifc reference model. Simulation results show that M-LWDF algorithm has slightly higher packet loss rate than EXP algorithm under the same conditions.
