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 ...
High-gain pattern reconfigurable MIMO antenna array for wireless handheld terminals
(The Institute of Electrical and Electronics Engineers, 2016)
The analysis, design, experimental development, and test results of a high-gain pattern reconfigurable antenna array are presented. Unlike traditional phased arrays, the proposed array has a compressed footprint making it ...
Cognitive security of wireless communication systems in the physical layer
(Wiley-Hindawi, 2017)
While the wireless communication systems provide the means of connectivity nearly everywhere and all the time, communication security requires more attention. Even though current efforts provide solutions to specific ...
Resource allocation with partially overlapping filtered multitone in cognitive heterogeneous networks
(IEEE-Inst Electrical Electronics Engineers INC, 2016)
Partially overlapping tones have recently been offered as a new solution to reduce the other user interference in cognitive heterogeneous networks. By introducing intentional carrier frequency shift, the users can exploit ...
