The development of 5G terrestrial mobile communications technology has been a driving
force for revolutionizing satellite mobile communications. Satellite mobile communications …

In 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 …

Multibeam satellite networks in Ka band have been designed to accommodate the
increasing traffic demands expected in the future. However, these systems are spectrum …

The usable satellite spectrum is becoming scarce due to continuously increasing demand
for broadcast, multimedia and interactive services. In this context, cognitive satellite …

Cognitive radio has attracted considerable attention because of its ability to make full use of
the available spectrum resources for wireless terrestrial communication networks. In …

The lack of available unlicensed spectrum together with the increasing spectrum demand by
multimedia applications has resulted in a spectrum scarcity problem, which affects satellite …

Applicability of cognitive radio (CR) techniques to satellite communications is investigated
and classification for the possible applications is foreseen in this paper. The proposed …

Nowadays both satellite and terrestrial networks are expanding rapidly to meet the ever-
increasing demands for higher throughput, lower latency, and wider coverage. However …

Future wireless networks will be required to provide more wireless services at higher data
rates and with global coverage. However, existing homogeneous wireless networks, such as …

This paper presents initial results of the recently kicked-off FP7 ICT STREP project
“CoRaSat”(Cognitive Radio for Satellite Communications)[1]. Focus is put on the preliminary …
