Enhancing the performance of low priority SUs using reserved channels in CRN
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
Cognitive radio networks (CRNs) are considered a promising solution for spectrum resources scarcity and efficient channel utilization. In this letter, multi-dimensional analytical Markov model based on reservation channel ...
Generalized coordinated multipoint framework for 5G and beyond
(Institute of Electrical and Electronics Engineers Inc., 2021)
The characteristic feature of 5G and beyond networks is the diversity of services, which is required to support different user needs. However, the requirements for these services are often competing in nature, which impresses ...
A hybrid downlink NOMA with OFDM and OFDM-IM for beyond 5G wireless networks
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
In this paper, a hybrid power domain non-orthogonal multiple accessing (NOMA) scheme by the superposition of orthogonal frequency division multiple accessing (OFDM) and index modulated OFDM (OFDM-IM) technologies is presented ...
Evaluation of the clinical features of 81 patients with covid-19: An unpredictable disease in children
(Georg Thieme Verlag, 2021)
Objective Data on the prognosis of clinical features of pediatric patients affected by the coronavirus disease 2019 (COVID-19) pandemic is insufficient. This study aimed to examine the clinical, laboratory, and radiology ...
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 ...
Flexible guard structure for timing synchronization in coordinated networks
(Institute of Electrical and Electronics Engineers Inc., 2022)
In this letter, a novel and flexible hybrid guard duration (HGD) based on zero tail (ZT) and cyclic prefix (CP) concepts is proposed for facilitating timing synchronization (TS) in coordinated multi-point (COMP) networks. ...
New physical layer key generation dimensions: Subcarrier indices/positions-based key generation
(Institute of Electrical and Electronics Engineers Inc., 2021)
In this letter, novel algorithms for secret key generation from the wireless channel in multi-carrier systems are proposed for ensuring the confidentiality and authentication in wireless communication systems. The novelty ...
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 ...
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 ...
Performance analysis of OTFS under in-phase and quadrature imbalance at transmitter
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2021)
The influence of in-phase and quadrature (IQ) imbalance on the performance of orthogonal time frequency space (OTFS) transmission is investigated in this work. OTFS is a recent two-dimensional transmission scheme with ...
