When cognitive radio (CR) systems dynamically use the frequency band, a control signal is necessary to indicate which carrier frequencies are currently available in the network. In order to keep efficient spectrum utilization, this control signal als

A noise suppression technique using overlapped FFT for carrier sensing of cognitive radio is proposed. The energy detection method is modified. A broadband signal is FFTed and the averaged power of each bin throughout the carrier-sensing period is ca
