Abstract

A spectrum sensing method in cognitive radio (CR) based on the third order cyclic cumulant (TOCC) according to the third order cyclostationarity of the most primary user (PU) signals is proposed in this paper. The binary hypothesis test model and the test statistic are constructed and the explicit formula of the detection probability under a constant false alarm rate (CFAR) is derived exploiting the asymptotic optimal estimation theory. The computational complexity can be decreased greatly by the improved algorithm. Simulation results are presented to illustrate the superior detection performances of the proposed spectrum sensing scheme.
