Abstract

This paper clarifies necessity of cognitive radio systems (CRSs) and introduces two approaches for their realization; heterogeneous type and spectrum sharing type. Both types of the CRSs have been developed for verification and evaluation. Large part of their design has been adopted as IEEE 1900.4. The systems are currently operated in a city-size test-bed for practical verifications. In the exhibition of CrownCom2011, the two types of CRSs are demonstrated.

Keywords: cognitive radio system; heterogeneous wireless network; spectrum sharing; cognitive wireless router; prototype; standardization
