Compact dual-band implantable antenna for e-health monitoring
(Institute of Electrical and Electronics Engineers, 2017)
This work presents a compact dual-band Planar Inverted F-antenna (PIFA) antenna useful for E-health monitoring and wireless sensors systems. The antenna operates in the Industrial Standard and Medical (ISM) and Wireless ...
A novel EBG structure to improve isolation in MIMO antenna
(Institute of Electrical and Electronics Engineers, 2017)
A new, and advanced Electromagnetic Band Gap (EBG) structure is reported to reduce the mutual coupling between two tightly spaced rectangular patch antennas. The EBG structure provides more than 20 dB reduction in mutual ...
Mutual coupling reduction in array elements using EBG structures
(Institute of Electrical and Electronics Engineers, 2017)
A 2D electromagnetic band gap (EBG) structure is designed on the ground plane of 1×2 rectangular patch antenna array to reduce the mutual coupling between the two elements and enhance the radiation pattern. An isolation ...
Enhancing the security performance of ostbc using pre-equalicodization
(Institute of Electrical and Electronics Engineers Inc., 2017)
In this study, we first quantify the secrecy performance achieved by employing precoded orthogonal space time block coding (POSTBC) in order to use it as a benchmark for comparison purposes with a new proposed security ...
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 ...
An efficient security method based on exploiting channel state information (CSI)
(Institute of Electrical and Electronics Engineers Inc., 2017)
A channel amplitude quantization method that can effectively quantize the channel response using just one single threshold value is proposed in order to extract a random manipulating sequence with good secrecy properties. ...
User association techniques in future heterogeneous networks
(Institute of Electrical and Electronics Engineers Inc., 2017)
The exponential increase in the demand of data rate and scarcity of the available spectrum have evolved to the more advanced network topology which efficiently utilizes the radio spectrum such as Heterogeneous Networks ...

(Institute of Electrical and Electronics Engineers Inc., 2016)
Waveforms proposed for future communication systems aim at fulfilling the demanding requirements of the next generation of 5G applications. In this paper, an enhancement over Zero Tail Discrete Fourier Transform Spread ...
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 ...
Enhancing physical-layer security in wireless communications using signal space diversity
(Institute of Electrical and Electronics Engineers Inc., 2016)
In this paper, we enhance the security of OFDM systems in frequency selective fading channels using signal space diversity. In rich multipath environments, spatially separated channels are independent to each other. Hence, ...
