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 ...
Deconvolution based light field extraction from a single image capture
(IEEE Computer Society, 2018)
In this paper, we propose a method to extract light field using a conventional camera from a single image capture. The method involves an offline calibration process, where point spread functions, relating different ...
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
(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 ...
Waveform design for 5G and beyond
(Wiley, 2018)
5G is envisioned to improve major key performance indicators (KPIs), such as peak data rate, spectral efficiency, power consumption, complexity, connection density, latency, and mobility. This chapter aims to provide a ...
Fm channel model development and its emulator
(Institute of Electrical and Electronics Engineers Inc., 2018)
With the widespread availability of Internet, voice only broadcast in the FM Band will soon be abandoned as Internet Radio can provide the same content with no boundaries. The available band can then be exploited for ...
Low complexity peak-to-average power ratio reduction in OFDM-IM
(Institute of Electrical and Electronics Engineers Inc., 2018)
Orthogonal frequency division multiplexing with index modulation (OFDM-IM) employs the indices of the active subcarriers for information transmission, as an alternative to conventional OFDM. It offers high spectral efficiency ...
On directional modulation: An analysis of transmission scheme with multiple directions
(Institute of Electrical and Electronics Engineers, 2015)
Increasing the spectral efficiency was always the motivation behind the evolution of wireless communication systems. Also, due to the widespread usage of wireless systems, securing the transmitted data rises as a main ...
