Reconfigurable intelligent surface (RIS): Eigenvalue decomposition-based separate channel estimation
(Institute of Electrical and Electronics Engineers Inc., 2021)
Reconfigurable intelligent surface (RIS) has recently drawn significant attention in wireless communication technologies. However, identifying, modeling, and estimating the RIS channel in multiple-input multiple-output ...
The effect of nebulized antibiotics in children with tracheostomy
(Elsevier Ireland Ltd, 2021)
Introduction: Children with tracheostomy have an increased risk of bacterial colonization and infection of the lower respiratory tracts. This study aimed to investigate the effects of nebulized antibiotics on the bacterial ...
Precoding based cross-tier interference mitigation in centralized-RAN
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2021)
This letter considers a two-tier downlink interference problem as a case of study, where macrocell user equipment (UE) shares the same frequency band with femtocell UE and suffers from severe cross-tier interference. Power ...
Numerology scheduling for PAPR reduction in mixed numerologies
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2021)
The flexible mixed-numerology structure with orthogonal frequency division multiplexing (OFDM) waveform is a key enabler to meet the requirements of various applications in fifth-generation (5G) and beyond wireless 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 ...
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 ...
A secure downlink NOMA scheme against unknown internal eavesdroppers
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2021)
Enhancing security level against potential internal eavesdroppers in Non-Orthogonal Multiple Access (NOMA) has been reported as a serious challenge. In this letter, a novel secure NOMA scheme based on physical-layer security ...
A novel frame design for integrated communication and sensing based on position modulation
(Institute of Electrical and Electronics Engineers Inc., 2021)
In this paper, a novel frame design for integrated communication and sensing is proposed. The proposed frame structure consists of Barker radar sequence and binary phase shift keying (BPSK) modulated data bits. The temporal ...
