Impact of Key Techniques on Packet Traffics in LCR TDD Systems

  • 摘要: 该文研究了LCR TDD系统中先进的RRM(无线资源管理)算法及其它关键技术对分组业务的影响,提出了一种基于速率预测的正比公平算法,通过动态系统级仿真得出结合智能天线(SA)或联合检测(JD)的不同调度算法对于数据业务吞吐量的改善,并横向对比了以上关键技术分别对于系统性能提升的作用。最后通过对仿真结果的评估,可以发现采用联合检测与智能天线相结合,并使用新的RRM算法不仅能够保证服务用户的公平性,而且对处于交叉时隙的分组数据用户的吞吐量的改善也是很明显的。
