Cognitive Satellite Terrestrial Radios
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010In this paper we present the concept of cognitive satellite terrestrial radios (CSTR) for hybrid satellite-terrestrial systems (HSTS). The cognitive radio (CR) technology is being motivated by the radio regulatory bodies for efficient utilization of the radio spectrum.

Deployment of Cognitive Radio in India
Wireless Personal Communications, 2014Cognitive radio is much talked as solution to limited spectrum resource. Provisions for deployment of cognitive radio have already been made in most of the EU countries, USA and Canada. It has not yet been introduced in India. This paper describes the frequency allocation for different services in Indian national frequency allocation plan.

Deep CM-CNN for Spectrum Sensing in Cognitive Radio
IEEE Journal on Selected Areas in Communications, 2019One of the key problems in spectrum sensing is to design the test statistic. Existing methods generally exploit the model-based features as the test statistic, such as energies and eigenvalues.

Radio logicielle, radio cognitive
2013Il y a 20 ans déjà que la radio logicielle a été définie conceptuellement dans l’article fondateur de Joe Mitola III de 1995 sur la “software radio architecture” paru dans l’IEEE Communications Magazine. Comme c’est souvent le cas dans les secteurs technologiques, les militaires (DoD, Department of Defense des Etats-Unis) ont été précurseurs dans le ...
