摘要 无线信道的非理想特性会使用户设备反馈给演进型基站(eNode B)的下行信道质量指示(CQI)参数值产生误差,从而降低调度器灵活调度的性能。为此,给出一种基于修正CQI反馈参数的快速分组调度方法,该方法在指数平滑预测模型及二次移动平均预测模型的基础上,利用CQI先验信息,通过组合预测对eNode B接收到的CQI参数值进行修正。仿真结果表明,该方法的吞吐性能够得到有效提升。 Scheduler can not work well for wireless channel which causes Channel Quality Indicator(CQI) parameter error when transporting for eNode B.A modified CQI-based packet schedule method for Long Term Evolution(LTE) is proposed.This method is based on the exponent smoothing forecast model and secondary moving average forecast method,combining priori parameters.Simulation result indicates that it can improve the throughput when scheduling.
