Research on Channel State Prediction Algorithm under Multi-radio Multi-channel Environment in Heterogeneous Networks

  • 摘要: 该文针对异构网络环境未知性的特点,基于部分可测马尔科夫(POMDP)模型,结合认知无线电频谱侦测技术,提出了一种新的多无线电多信道环境下信道状态预测算法。该算法通过对信道状态历史信息的分析,推导出信道信念状态(belief state)的初始分布和转移概率,并以此选择出具有最佳回报的信道以供接入,从而达到提高信道利用率的目的。仿真结果表明算法性能要优于传统算法。
