Abstract
Disclosed is a cooperative spectrum sensing (CSS) method. The CSS method includes receiving, by a detector of secondary users, observation vectors which are use state information of a spectrum band allocated to a PU in a cognitive radio (CR) network, generating, by the detector, an analysis result value with respect to each of the observation vectors using GLRT with respect to order statistics of reception samples taking non-Gaussian noise into consideration, transmitting, by the detector, the analysis result value to a fusion center unit; and fusing, by the fusion center unit, the analysis result value to determine whether the spectrum band is used.
