| Abstract(in English) | The increase in the number of wireless systems is creating a serious shortage of space in the radio spectrum. Cognitive radio technology is receiving particular attention as a technology that solves this problem. A cognitive radio system dynamically uses vacant spectrum and works adaptively by sensing channel environments and their availability. Spectrum sensing technology is an important elemental technology for recognizing channel environments. Energy detection, cyclostationary detection and cooperative sensing methods have been studied as spectrum sensing technology. Cooperative sensing methods can improve the detection capability of a secondary system because it determines whether a primary system is present or not based on the detection results of multiple terminals. The problem is that the performance of cooperative sensing method is affected by the method used to determine whether the primary system is present and the sensing information used to make that decision. We have developed a cooperative sensing method of putting weight based on a reliability of sensing information gathered from each terminal. We evaluated the method's performance by computer simulation. Moreover, we demonstrated that our proposed method is effective on a laboratory test bed. |
