A Novel Detection Scheme Based on Uplink Timeslots

Fang Jian1,Huang Biao1,Zhou Xianwei2,Huang Qiuxiang3(1.State Radio Monitoring Center,Beijing 100083,China;2.University of Science and Technology Beijing,Beijing 100083,China;3.Western Mining Co.,Ltd.,Xining 810001,China)  
In this paper,a novel detection scheme will be introduced into the CR system,which have uplink timeslots and downlink timeslots,based on the different transmit power of base station(BS) and User Equipment(UE).If the CR nodes of unauthorized users carry on the on-line energy detection,it will be subject to the interference originated from its own BS.A new detection program employed only in the uplink timeslots is proposed.In this program,the interference,which is coming from its own UE,may be weaker than it originated from BS.The paper researched the CR system,in which TD-LTE system is the unauthorized user and the radar system is authorized user.Through theoretical analysis and simulation,the feasibility of the new program has been verified.
