Abstract(in English) In a cooperative spectrum sensing system, many nodes perform spectrum sensing and report their decisions to one fusion center via control channels. This paper considers the efficient use of the frequency band for the control channels. For this purpose, We have proposed a sequential-test-based scheme. With this scheme, necessary maximum bandwidth for the control channels decreases. This paper shows impact of bandwidth canstraints on the proposed scheme. Numerical results show that the proposed scheme has higher detection accuracy than a simply truncated sequential-test-based scheme.
