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 ...
A MEMS T/R switch embedded in CMUT structure for ultrasound imaging frontends
(IEEE Computer Society, 2016)
This paper describes a novel MEMS transmit/ receive (T/R) switch that could be embedded in the general structure of a capacitive micromachined ultrasonic transducer (CMUT). A MEMS switch and a CMUT element were fabricated ...
CMUTs on glass with ITO bottom electrodes for improved transparency
(IEEE Computer Society, 2016)
In this work, we fabricated capacitive micromachined ultrasonic transducers (CMUTs) on a glass substrate with indium tin oxide (ITO) bottom electrodes for improved transparency. A 2-µm vibrating silicon plate was formed ...
Secret key generation using channel quantization with SVD for reciprocal MIMO channels

Microwave heating of heavy oil and bitumen
(Institute of Electrical and Electronics Engineers Inc., 2016)
A theoretical study is presented for the feasibility of a microwave heating device that will raise the temperature of heavy oil and bitumen reservoir. The device is enclosed in a radome which is surrounded by a perforated ...
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 ...
