Abstract (in Japanese) (See Japanese page) 
(in English) Recently, study of cooperative spectrum sensing has been focused on, which can improve the sensing accuracy for primary radio system (PR) by
sharing the sensing result among secondary users (cognitive radio users (CR)).
In this study, we adopt VOTE-rule as the judging rule in the cooperative sensing.
Applying cooperative sensing to the practical use, we should consider the distance between CRs and PR.
We propose the improved VOTE-rule which reduce miss detection probability with setting acceptable false alarm probability.
We show that it makes cooperative sensing more correctly than using the conventional VOTE-rule which doesn't change the number threshold and ensures the transmission opportunity of CRs.
In addition, we consider that there are two PRs.
We propose to form the groups which are assigned to each PR and judge assigned PR's present.
We show that its selected method can reduce miss detection more than the method which judge from all CRs.
And then, we show that combinating selected cooperative CR nodes with the improved VOTE-rule can reduce miss detection probability more.
