Description
Summary:The rapid growth in wireless communications has contributed to a massive demand on the deployment of new wireless services in both the licensed and unlicensed frequency spectrum. To address the poor spectrum utilization problem, cognitive radio has emerged as a promising technology to enable the access of unused frequency bands and thereby increase the spectral efficiency. Hence, one main aspect of cognitive radio network is related to autonomously exploiting locally unused spectrum to provide new paths to spectrum access. This study presents recent developments and open research challenges in spectrum key functionalities in cognitive radio network.
