主　　题：cognitive radio(CR) cyclostationarity noise uncertainty spectrum sensing 

摘      要：Cognitive radio(CR)is a promising *** most fundamental problem of CR is spectrum *** detector is often considered for spectrum sensing in CR,and if the noise power is exactly known,energy detector has admirable ***,in practice,noise power is always inexactly *** solve this problem,Dandawate[Dandawate et *** Transactions on Signal Processing,1994,42(9):2355-2369]has proposed a nonparametric single-cycle detector based on cyclostationarity,which is robust to noise *** this paper,based on Dandawate’s single-cycle detector,a joint multi-cycle detector is further proposed,which is also nonparametric and immune from noise *** results have shown the validity and superiority over single-cycle detector of the proposed detector.
