Abstract
Goodness of fit tests have been used to find available spectrum in cognitive radio system. In this paper, a unilateral Right-tail Anderson-Darling (URAD) criterion, one of goodness of fit test, is introduced and a blind spectrum sensing scheme based on URAD criterion by using Student’s distribution is proposed for multiple antennas cognitive radio system. The spectrum sensing is reformulated as a unilateral Student’s testing problem, and the URAD criterion is employed to sense the available spectrum. Numerical simulations verify that the proposed spectrum scheme is robust to noise uncertainty, and greatly outperforms five classical spectrum sensing schemes.
