DOI: 10.1109/tcomm.2018.2880765
Abstract: This paper considers an unlicensed multiple-access channel (MAC) that coexists with a licensed point-to-point user, following the underlay cognitive radio paradigm. We assume that every transceiver except the secondary base station has one antenna and… read more here.

DOI: 10.1109/tcomm.2023.3253688
Abstract: Proactive eavesdropping is an effective approach to improve the performance of wireless information surveillance, where suspicious users are legitimately eavesdropped by authorized monitors. For the situation when no monitor is available, we propose to authorize… read more here.
