摘要：

This paper fouces on the spectrum handoff in cognitive radio which secondary users(SU) usually use the overlay spectrum acess scenario. We use the fuzzy logic and pridect a reserved channel table, when the spectrum handoff occur, SU can choose the available spetrum access quickly. Because of primary users(PU) appear uncertainty, the correctness of backup channel can not ensure. To aim at this problem, we decrease the error of table via detecting spectrum occupation rate real-time to update backup channel table in this paper. Simulation result show that our proposed scheme can reduce the handoff delay, increase the correctness of reserved channel table and improve the effective data rate.
