We address secure resource allocation for an OFDMA cooperative cognitive radio network (CRN) with energy harvesting (EH) capability. In the network, one primary user (PU) cooperates with several untrusted secondary users (SUs) with one SU transmitter and several SU receivers, where the SU transmitter and all SU receivers may overhear the PU transmitter's information while all SU receivers may eavesdrop...
Passive radar network systems utilize multiple transmitters of opportunity and multichannel receivers to offer remarkable performance improvement due to the advantage of signal and spatial diversities. The frequency modulation (FM) commercial radio signals have become attractive for passive radar applications owing to their wide-spread availability and the favourable Doppler resolution. In this paper,...
Cooperative cognitive radio (CCR) is a novel paradigm for improving both radio spectrum efficiency and communication quality. However, for the CCR networks with energy harvesting, how to achieve specific relay selection is still an open issue. In this paper, we consider a CCR network with energy harvesting in which multiple secondary transmitters are able to harvest energy from the received signals...
