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.
