PROJECT TITLE :

Impact of Cognitive Radio: Recognition and Informed Exploitation of Grey Spectrum Opportunities

ABSTRACT:

All spectrum opportunities are not created equally. The diverse behavior of different primary users (PUs) in various spectrum bands affects a cognitive radio's ability to exploit spectrum holes. In a heavily used spectrum environment, the availability of unutilized, uncluttered, and easily accessible white space spectrum is unlikely. Rather, cognitive radios must explore the gray spectrum, those bands in which other users exist and in which the existence of exploitable spectrum holes is more difficult to discern and access.
