Resum
Cognitive Radio (CR) is aimed at increasing the e ffi ciency of spectrum utilization by allowing unlicensed users to access, in an op- portunistic and non-interfering manner, some licensed bands temporarily and / or spatially unoccupied by the licensed users. The analysis of CR sys- tems usually requires the spectral activity of the licensed system to be rep- resented and characterized in a simple and tractable, yet accurate manner, which is accomplished by means of spectrum models. In order to ...
