Abstract
Applicability of cognitive radio (CR) techniques to
satellite communications is investigated and
classification for the possible applications foreseen in
this paper. The proposed application scenarios include a)
secondary use of satellite spectrum by a terrestrial
system, b) secondary use of terrestrial spectrum by a
satellite system, and c) a hybrid scenario where
terrestrial network coverage is expanded by the use of
satellite spots. Key challenges and enabling technologies
for each scenario are discussed. Link budget analysis and
simulations are used to define operational limits for
interference management in the mentioned scenarios
regarding spectrum sensing, transmission power control,
and directional antennas. The results show that CR
techniques should be applied with caution in satellite
bands. However, obvious potential to improve the spectrum
use can be seen in each scenario.
