On reducing multiband spectrum sensing duration for cognitive radio networks
(Institute of Electrical and Electronics Engineers Inc., 2016)
In this work, the total spectrum sensing duration required for cognitive radios in multiband environments is studied to minimize the reactive handoff latency. Two spectrum sensing strategies, namely window-based and ...
Zero tail filter bank spread OFDM
(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 ...
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, ...

(Institution of Engineering and Technology, 2016)
Technological advances in biomedical engineering have significantly improved the quality of life and increased the life expectancy of many people. In recent years, there has been increased interest inwireless body area ...
Secure multiple-users transmission using multi-path directional modulation
(Institute of Engineers and Everyone Else, 2016)
This work introduces a physical-layer secure multiple-users communication scheme. Our scheme employs the multi-path nature of the wireless channel to provide a different secure communication link for each of the legitimate ...
Suppressing alignment: Joint PAPR and out-of-band power leakage reduction for OFDM-based systems
(Ieee-Inst Electrical Electronics Engineers Inc, 2016)
Orthogonal frequency division multiplexing (OFDM) inherently suffers from two major drawbacks: high out-of-band (OOB) power leakage and high peak-to-average power ratio (PAPR). This paper proposes a novel approach called ...
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 ...
Freeman-Sheldon syndrome associated with hemophilia-a in a newborn
(Galenos Yayıncılık, 2016)
The Freeman-Sheldon syndrome (FSS) (whistling face) is a congenital autosomal dominant disease (rarely described in its autosomal recessive form) characterized by small "whistling" mouth, a flat masklike face, joint ...
