Kentaro Ishizu, Homare Murakami, Hiroshi Harada · 2011
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.
