Abstract
In this paper, we propose an inband and outband broadcast method for hidden incumbent system detection of MAC layer for WRAN systems using cognitive radio technology. In order to make sure that cognitive radio WRAN system must be operated with no interference to incumbent system, WRAN system should sense channel during its communication and change channel according to the appearance of incumbent system. To detect hidden incumbent system, we use some extra candidate channels to broadcast current channel list and to report CPE's sensing results. © 2008 Springer Berlin Heidelberg.
