主　　题：cognitive radio energy detection basis function 

摘      要：As cognitive radio (CR) needs to detect spectrum accurately and utilize the idle spectrum efficiently,a new model of CR is *** model adopts energy detection with auto-adapted threshold and produces spectrum mark *** basis function is obtained through making IDFT to the inner product of spectrum and phase vectors,and it is variable with the spectrum *** are sent through modulation on the basis function,and it can be estimated by correlation in the receiving *** cooperative detection and multiple access of this model are also researched in this paper,and the performance is finally *** show the cooperative detection of this model can obtain higher detection probability,and the disaccord of the basis functions between sending and receiving ends can lower its performance.
