Emulation techniques for small scale fading aspects by using reverberation chamber
(Ieee-Inst Electrical Electronics Engineers Inc, 2019)
Reverberation chambers (RVCs) are used to provide an efficient and reliable testbed for emulating the wireless channel effects in the laboratory environment. In the literature, various techniques have been studied to enrich ...
Joint phy/mac layer security design using arq with mrc and null-space independent papr-aware artificial noise in siso systems
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2018)
Automatic-repeat-request (ARQ) as a MAC layer mechanism and artificial noise (AN) as a physical layer mechanism along with the help of maximal ratio combining (MRC), are jointly designed to achieve secrecy. Basically, a ...
Theoretical analysis of the co-existence of LTE-A signals and design of an ML-SIC Receiver
(Institute of Electrical and Electronics Engineers, 2015)
The increasing number of mobile devices and the demand for large throughput requiring applications has hampered access to the limited frequency spectrum. The goal of this work is to introduce a new degree of freedom to the ...
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 ...
Utilization of aerial heterogeneous cellular networks: Signal-to-interference ratio analysis
(Korean Institute of Communications and Information Sciences (K I C S), 2018)
As a component of future communication networks, aerial telecommunication platforms are a promising solution to meet surging traffic demands. These platforms can be used as aerial base stations (ABSs) to build an aerial ...
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

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 ...
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 ...
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 ...
