| 摘 要： | 在保证用户间公平性的前提下,为尽量提高cdma2000的增强型1xEV DO系统前向链路的数据吞吐量,通过讨论现有的多种调度算法原理,分析了影响系统吞吐量和公平性的因素,在此基础上提出将用户平均请求传输速率、限制用户最小平均传输速率和系统最小吞吐量的影响同时引入调度算法的思想,通过在CadenceSPW软件平台上的仿真研究表明,改进后的调度算法在保持公平性的前提下,有效提高了系统前向链路吞吐量.

| Abstract: | In order to improve the throughput on the forward link of cdma2000 1x EV-DO system and guarantee fairness to the users, the principles of the existing scheduling algorithms were discussed and the factors which influenced throughput and fairness were studied. A new scheduling algorithm which was based on the average requested rate of the users and the minimum limits in the average transmission rate and the throughput of system was introduced. The proposed algorithm proved to be superior to others, because total average throughput increased and fairness was guaranteed through the simulation on the software platform of Cadence SPW. |
