摘要 认知无线电是一种智能频谱共享技术,它通过自适应频谱感知寻找"频谱空穴",智能学习并实时调整传输参数,实现频谱动态分配和频谱共享,显著改善现有频谱利用率。概括介绍了CR的QoS方案研究现状,并指出目前研究存在的问题以及可进一步研究的方向。 Cognitive radio is an intelligent spectrum sharing technology. It does this by looking for adaptive spectrum sensing ＂spectrum hole＂, intelligent learning and real-time adjustment of transmission parameters to achieve dynamic spectrum allocation and spectrum sharing, significantly improving the existing spectrum efficiency, the article detailedly introduces the current CR research status of QoS. At last, pointing out the problems and further research tendency.
