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 ...
Physical layer authentication scheme in beamspace MIMO systems
(Institute of Electrical and Electronics Engineers Inc., 2022)
The broadcast nature of wireless communication makes it vulnerable to various security threats such as spoofing attacks. Physical layer (PL) authentication has emerged as a promising and powerful approach to secure future ...

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
