Cross MAC/PHY layer security design using ARQ with MRC and adaptive modulation
(Institute of Electrical and Electronics Engineers Inc., 2016)
In this work, Automatic-Repeat-Request (ARQ) and Maximal Ratio Combination (MRC), have been jointly exploited to enhance the confidentiality of wireless services requested by a legitimate user (Bob) against an eavesdropper ...
A practical physical-layer security method for precoded OSTBC-based systems
(Institute of Electrical and Electronics Engineers, 2016)
In this work, we investigate the security performance obtained by employing a practical precoded orthogonal space time block coding method (POSTBC) in MISO wireless networks. In particular, space time codewords are precoded ...
Secret key generation using channel quantization with SVD for reciprocal MIMO channels
(IEEE, 2016)
The generation of secret keys from reciprocal wireless channel by exploiting their randomness nature, is an emerging area of interest to provide secure communication. One of the main challenges in this domain is to increase ...
Controlled inter-carrier interference for physical layer security in OFDM systems
(Institute of Electrical and Electronics Engineers Inc., 2016)
Performance of OFDM is known to be very sensitive to frequency synchronization errors. By exploiting this feature, a novel technique is proposed to provide secure communication against eavesdropping. The technique is based ...
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 ...

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 ...
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 ...
