OFDM with index modulation for asynchronous mMTC networks
(MDPI, 2018)
One of the critical missions for next-generation wireless communication systems is to fulfill the high demand for massive Machine-Type Communications (mMTC). In mMTC systems, a sporadic transmission is performed between ...
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 ...
Time-frequency warped waveforms
(IEEE-Inst Electrical Electronics Engineers Inc, 2019)
The forthcoming communication systems are advancing toward improved flexibility in various aspects. Improved flexibility is crucial to cater diverse service requirements. This letter proposes a novel waveform design scheme ...
Joint time-frequency alignment for PAPR and OOBE suppression of OFDM-based waveforms
(IEEE-Inst Electrical Electronics Engineers Inc, 2017)
Orthogonal frequency division multiplexing (OFDM) waveform has been adopted by many wireless standards due to its numerous advantages. However, OFDM symbols have two critical drawbacks: high out-of-band emission (OOBE) and ...
Guard band reduction for 5G and beyond multiple numerologies
(IEEE, 2020)
The existence of inter-numerology interference (INI) is a major drawback for the flexible multi-numerology frame structure proposed for the upcoming fifth generation New Radio (5G-NR). Insertion of a guard band (GB) between ...
Inter-numerology interference for beyond 5G
(Institute of Electrical and Electronics Engineers Inc., 2019)
Fifth generation (5G) radio access technology (RAT) is designed to flexibly serve multiple services with extremely diverse requirements. One of the steps taken toward fulfilling this vision of 5G-RAT is the introduction ...
Flexible physical layer security for joint data and pilots in future wireless networks
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2022)
In this work, novel physical layer security (PLS) schemes are proposed for orthogonal frequency-division multiplexing (OFDM) to secure both data and pilots in multiple-input multiple-output (MIMO) systems. The majority of ...
Primary user emulation and jamming attack detection in cognitive radio via sparse coding
(Springer, 2020)
Cognitive radio is an intelligent and adaptive radio that improves the utilization of the spectrum by its opportunistic sharing. However, it is inherently vulnerable to primary user emulation and jamming attacks that degrade ...
Comparison of clinical and laboratory features and treatment options of 237 symptomatic and asymptomatic children infected with SARS-CoV-2 in the early phase of the COVID-19 pandemic in Turkey
(National Institute of Infectious Diseases, 2021)
Since the first report of COVID-19 in December 2019, little is known about therapeutic usage of hydroxychloroquine in pediatric patients with COVID-19. We retrospectively retrieved data for SARS-CoV-2 PCR positive pediatric ...
NOMA for multinumerology OFDM systems
(Wiley Hindawi, 2018)
Nonorthogonal multiple access (NOMA) is a promising technique which outperforms the traditional multiple access schemes in many aspects. It uses superposition coding (SC) to share the available resources among the users ...
