Rf circuit implementation of a real-time frequency spread emulator
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2018)
Despite their reliability, on-site measurements are time-consuming and costly actions for the evaluation of new devices. Channel emulators are widely utilized measurement instruments to generate desired environmental channel ...
Partially overlapping tones for uncoordinated networks
(Institute of Electrical and Electronics Engineers, 2014)
In an uncoordinated network, the link-level performance of a wireless receiver might degrade significantly due to the interference from other transmitters that share the same spectrum. As a solution, in this study, the ...
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 ...
Suppressing alignment: Joint PAPR and out-of-band power leakage reduction for OFDM-based systems
(Ieee-Inst Electrical Electronics Engineers Inc, 2016)
Orthogonal frequency division multiplexing (OFDM) inherently suffers from two major drawbacks: high out-of-band (OOB) power leakage and high peak-to-average power ratio (PAPR). This paper proposes a novel approach called ...
A windowing technique for optimal time-frequency concentration and aci rejection in ofdm-based systems
(Institute of Electrical and Electronics Engineers, 2015)
In this paper, we introduce a windowing technique, which provides optimal time-frequency containment and maximal adjacent channel interference (ACI) rejection for orthogonal frequency-division multiplexing (OFDM)-based ...
Dynamic sidelobe multiplexing in beamspace MIMO systems
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)
Recent studies on multiplexing concept over beamspace multiple-input-multiple-output (MIMO) can reduce the need for using phase shifters while keeping the directivity performance at similar levels. Thus, beamspace MIMO ...
Partially overlapping filtered multitone with reconfigurable antennas in uncoordinated networks
(Elsevier Sciences Bv, 2017)
Partially overlapping tones (POT) have recently been offered as a promising solution with the aim of decreasing the interference induced on the users for uncoordinated networks. Since each user causes interference on other ...
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 ...
User pairing and power allocation strategies for 3D VLC-NOMA systems
(Institute of Electrical and Electronics Engineers Inc., 2020)
In this letter, we propose two novel, yet efficient, user pairing schemes for non-orthogonal multiple access (NOMA) in 3D visible light communication (VLC). Our analysis is carried out assuming different heights for the ...
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. ...
