感知时延约束下认知无人机网络的快速频谱感知
Quick spectrum sensing for delay-constraint cognitive UAV networks
摘要
Abstract
Unmanned aerial vehicles(UAVs)without human operator are gained much popularity for a wide variety of applications,but also face the spectrum scarcity problem.A cognitive UAV network(CUAVN)framework based on cognitive radio(CR)technology is proposed,in which the sequential probability ratio test(SPRT)is used as a fundamental cooperative spectrum sensing(CSS)scheme.Considering the location flexibility and uneven distribution density of UAVs,an intra-frame CSS structure is designed,and a sequential maximal truncation(SMT)method is proposed to realize the quick spectrum sensing for delay-constraint CUAVNs.The results show that,compared to uniform tail truncation(UTT),the proposed quick multi-band spectrum sensing scheme with the help of SMT requires fewer sensing times,and has better sensing performance,especially under a strict delay constraint.关键词
