On the performance of subcarrier allocation techniques for multiuser OFDM cognitive networks with reconfigurable antennas
(Institute of Electrical and Electronics Engineers Inc., 2014)
Reconfigurable antennas (RA) have been viewed as a hardware-efficient alternative solution to multiple-input multiple-output systems whereby network users can vary the antenna radiation patterns using a single antenna ...

Channel independent physical layer security
(Institute of Electrical and Electronics Engineers Inc., 2016)
Security is one of the key requirements of wireless communication systems. By exploiting the broadcast nature of wireless medium, a malicious user might attempt to mislead the legitimate nodes, intercept the communication ...
A survey: Spoofing attacks in physical layer security
(IEEE Computer Society, 2015)
Increasing demand on wireless communications also increases the issues related to communication security. Among different security solutions, physical layer security have recently been gaining many interests by the ...
Game theoretical partially overlapping filtered multi-tones in cognitive heterogeneous networks
(Institute of Electrical and Electronics Engineers Inc., 2014)
Partially overlapping tones have recently been paid attention to by the researchers in cognitive heterogeneous networks (HetNets). In this paper, we introduce partial overlapping in the filtered multi-tones instead of full ...
Joint subcarrier and antenna state selection for cognitive heterogeneous networks with reconfigurable antennas
(Institute of Electrical and Electronics Engineers, 2015)
Reconfigurable antennas (RA) offer an emerging technology that allows wireless devices to alter their antenna states determined by different radiation patterns to maximize received signal strength. In this paper, we consider ...
Partially overlapping filtered multitone with reconfigurable antennas in uncoordinated networks
(Elsevier Sciences Bv, 2017)
Partially overlapping tones (POT) have recently been offered as a promising solution with the aim of decreasing the interference induced on the users for uncoordinated networks. Since each user causes interference on other ...
