Abstract (in Japanese) (See Japanese page) 
(in English) In a cognitive radio system, a spectrum sensing is used as a technique for deciding a wireless environment instantly. In addition, the wireless environment is estimated by a statistical information which is collected from the sensing nodes toward a database of a cognitive station. This paper considers the system combined the sensing and the database. The database of the cognitive station is updated by receiving the sensing information from the sensing nodes. In the conventional researches, a statistical information of the database is periodically updated. However, this updating information consumes wireless resources. In this paper, the sensing node transmits the sensing information autonomously for updating the statistical information of the database based on the reliability of information and the sensing results.
