混沌超宽带光载无线电通信链路的地研究.pdf

太原理工大学硕士研究生学位论文最后,基于光反馈半导体激光器产生的混沌I】-WB信号,搭建了混沌UWB光载无线通信链路,实现了360,720Mbit/。在未经任何色散补偿处理的情况下,(SMF),在天线接收端被成功解调。由于混沌UWB信号输出的随机性,对应的UWB信号频谱中未出现任何离散的谱线。这意味着利用混沌UWB信号实现的光载无线通信链路,可以完全避免离散谱线对系统传输性能的劣化。关键词:半导体激光器,混沌激光,超宽带(UWB)信号,混沌超宽带光载无线电太原理丁大学硕士研究生学位论文DEMONSTRATl0NOFCHAOTICULTRAⅥDEBA八口DRADIO一0VER-FIBERCON瓜仉烈ICATl0NLINKABSTRACTRecentlyultrawideband(UWB),lowcost,highdatarates,,,.,withregularantennas,,researchersproposedUWBradio—over-fibertechnology,whichisthekeytechnologytorealizethe“seamlesscoverage”.Inthisdissertation,wedemonstrateanovelschemeofchaoticultrawidebandradio—over-municationlink,themainworksincluding:太原理工大学硕士研究生学位论文Firstly,paretheexistingopticalUWBgenerationtechnologies,pointoutthatregardlessofthebasebandormm—waveUWBSignalsgeneration,thehighfrequencyelectronicdeviceisnecessary,,themethodsbasedonGaussianpulseshapingtheoryaredifferenttocontrolthespectrumprofileofgeneratedpulse,,’,missionregulations.。Finally,weproposeandexperimentallydemonstrateachaoticUWBoverfiberlinkbasedonopticalfeedbacklaserdiode,inwhichUWBsignalsweregeneratedandtransmittedatthreedifferentbitratesof360,720
