Zaman gecikmeleriyle birlikte bozucu etkilere maruz kalan bir dc servomotorun geribeslemeli kontrolü
(2017)
Kablosuz kontrol sistemlerinde, kontrol sinyallerin iletiminde oluşan zaman gecikmeleri sistemin kararlı bir cevap üretmesini zorlaştırır. Özellikle ileri hatta ve geribesleme hattında oluşan toplam gecikmelerin etkisi ...
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 ...
Experimental characterization of in vivo radio channel at MICS and ISM Bands
(Electromagnetics Academy, 2015)
This paper presents an experimental study for the propagation losses and wave attenuation inside human body for implanted antenna at different body organs. The experimental study discusses the commonly used frequency bands: ...
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 ...
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 ...
Inter numerology interference analysis for 5G and beyond
(Institute of Electrical and Electronics Engineers Inc., 2018)
One of the defining characteristics of 5G is the flexibility it offers for supporting different services and communication scenarios. For this purpose, usage of multiple numerologies has been proposed by the 3rd Generation ...
Hybrid precoding for mm Wave massive MIMO systems with generalized triangular decomposition
(Institute of Electrical and Electronics Engineers Inc., 2018)
Hybrid precoding schemes have recently gained a great attention for millimeter wave (mmWave) massive multiple-input-multiple-output (massive MIMO) communication systems because of offered cost and low-power consumption ...
Discrete fourier transform spread zero word OFDM
(Institute of Electrical and Electronics Engineers Inc., 2017)
Fifth generation (5G) waveform must meet a superior performance in multipath channels along with low peak to average power ratio (PAPR), especially in up-link transmission. Among waveform candidates, zero tail (ZT) DFT-spread ...
A flexible hybrid waveform
(Institute of Electrical and Electronics Engineers Inc., 2017)
Cellular systems of fifth generation (5G) require a waveform with flexible guard interval length along with a low power consumption. Different cyclic prefix (CP) durations in long term evolution (LTE) result in loss of ...
