Published in 2019 at "IEEE Communications Letters"

DOI: 10.1109/lcomm.2019.2926461

Abstract: In this letter, we present a hybrid spectrum sharing approach in cognitive radio (CR) systems with dynamic users in which the secondary users (SU) may not accurately detect the presence of primary users (PU). As… read more here.

Published in 2019 at "IEEE Transactions on Communications"

DOI: 10.1109/tcomm.2019.2946309

Abstract: We consider the problem of making a quick decision in favor of one of two possible physical signal models while the numerical measurements are acquired by sensing devices featuring minimal digitization complexity. Therefore, the digital… read more here.

Published in 2022 at "IEEE Transactions on Vehicular Technology"

DOI: 10.1109/tvt.2021.3137627

Abstract: Identification of communication parameters, a major task of intelligent receivers, has important applications in intelligent systems, especially cognitive radio systems. Multiple antennas make the identification problem more challenging. In this paper, we focus on the… read more here.
