有限区域同时同频全双工跳频自组网性能研究段柏宇陈聪陈顺轲徐强邵士海*(电子科技大学通信抗干扰技术国家级重点实验室成都611731)摘要：该文针对有限区域的同时同频全双工(CCFD)跳频自组网络，通信节点位置不等价，受非对称互干扰和自干扰影响的场景，开展有限区域全双工跳频自组网的通信性能分析。以网络频带利用率为性能指标，推导出节点位置分布条件下的网络频带利用率闭合表达式，并提出一种降低网络互干扰的节点位置优化分布方法。理论和仿真结果表明，有限区域全双工跳频自组网的性能与频点个数、通信距离、节点个数强相关，且全双工自组网络的性能与半双工网络相比，其占优区域受节点个数约束。关键词：自组网；同时同频全双工；网络频带利用率；跳频通信中图分类号：TN911.7文献标识码：A文章编号：1009-5896(2023)02-0480-08DOI:10.11999/JEIT211499PerformanceAnalysisofCo-frequencyandCo-timeFullDuplexFrequencyHoppingAdHocNetworksinFiniteAreaDUANBaiyuCHENCongCHENShunkeXUQiangSHAOShihai(NationalKeyLaboratoryofScienceandTechnologyonCommunications,UniversityofElectronicScienceandTechnologyofChina,Chengdu611731,China)Abstract:ForCo-frequencyandCo-timeFullDuplex(CCFD)frequencyhoppingadhocnetworkinfinitearea,communicationperformanceanalysisisproposedconsideringthescenarioofself-interferenceandasymmetricmutualinterferencecausedbyunequalpositionofcommunicationnodes.Takingthenetworkbandutilizationastheperformanceindex,theclosedexpressionofnetworkbandutilizationundertheconditionofnodelocationdistributionisderived,andanodelocationoptimizationdistributionmethodreducingnetworkmutualinterferenceisproposed.Simulationresultsshowthattheperformanceoffullduplexfrequencyhoppingadhocnetworkinfiniteareaisstronglyrelatedtothenumberoffrequencypoints,communicationdistanceandthenumberofnodes.Besides,whethertheperformanceoffullduplexadhocnetworkisbetterthanhalfduplexnetworkdependsonthenumberofnodes.Keywords:Adhocnetworks;Co-frequencyandCo-timeFullDuplex(CCFD);Networkbandwidthutilization;Frequencyhoppingcommunication1引言无线自组织网络由于其分布式无中心和自组织协同特性，已开始应用于无人机集群、抢险救灾、安全反恐等领域[1–4]。目前，考虑到自组织...
