Abstract (in Japanese) (See Japanese page) 
(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 efficient use of the frequency band for the control channels. For this purpose, sequential-test is introduced for the local decision at each node. With this scheme, the transmission timing of the reports from nodes becomes at random and necessary maximum bandwidth for the control channels decreases.
Numerical results show that this sequential-test-base-scheme not only
decreases the number of simultaneous reports but also improves sensing reliability. For further improvement, this paper introduces a decision scheme at the fusion center based on probabilistic features of the reports from nodes.
