Abstract :Because a large number of licensed users have occasionally used their allocated bandwidth in recent years, efficient use of frequency band is a vital issue. While licensed users continue to use this bandwidth for publishing, unused bands can be allocated for reuse to provide broadband network services. These empty bands are described as white space and cover a large part of the bandwidth. It is possible to activate this great potential by cognitive radio technology. In this study, energy detection technique was used to detect unused bands. With this technique, it is determined which frequency band is suitable and there will be done appropriately the assignment of the second user.
