Enhancing Spectrum Hole Utilization Through Adaptive Sensing in Cognitive Radio Systems

Cognitive Radio (CR) is a new concept in wireless communication systems that aims at enabling dynamic access to the frequency spectrum for unlicensed Secondary Users (SU) through the reuse of licensed frequencies. Specifically, CR systems are expected to detect idle frequency bands that are not actively used by licensed Primary Users (PU) by applying a spectrum sensing procedure, to take advantage of them for providing service to SU, and to release them to the PU upon request.
