Original Abstract

Cognitive radios offer re-utilization of unused li- censed channels by establishment of secondary networks based on dynamic spectral sharing. A key aspect of CR networks is proper exploring of unused frequencies. In this paper, a well known sensing method employing repetitive properties of OFDM based signal was selected for implementation. The method is fully implemented into special wideband sensing platform and evaluated under signals of real DVB-T services. Implementation steps and baseband preprocessing are described. Moreover, a new approach of implementation of the test metric calculation is introduced.
