  • Abstract
    Spectrum sensing is an important functionality for cognitive radio (CR) systems and enables more efficient spectrum utilization in wireless systems through spectrum sharing. In this paper, we consider a CR system that uses spectrum sensing based on the Time-Domain Symbol Cross-correlation (TDSC) technique, and study its application in the context of the mobile WiMAX standard for which the TDSC method is explained analytically and illustrated with numerical results obtained from simulations.
