Non-redundant OFDM receiver windowing for 5G frames and beyond
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Contemporary receiver windowed-orthogonal frequency division multiplexing (RW-OFDM) algorithms have limited adjacent channel interference (ACI) rejection capability under high delay spread and small fast Fourier transformation ...
Multidimensional index modulation for 5G and beyond wireless networks
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2021)
Index modulation (IM) provides a novel way for the transmission of additional data bits via the indices of the available transmit entities compared with classical communication schemes. This study examines the flexible ...
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 ...
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 ...
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 ...
A spatially adaptive antenna array for mm-wave wireless channel control with microfluidics based reconfiguration
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)
Spatially adaptive antenna array (SAA) is an electronically scanned antenna array with capability of changing its physical location. This new capability allows SAA to control the wireless channel environment to increase ...
Radar-aided communication scheduling algorithm for 5G and beyond networks
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2022)
Radar and communication coexistence is an upcoming technology with numerous research opportunities in the medium access control (MAC) layer, particularly in scheduling and radio resource management (RRM). More efficient ...
OFDM with hybrid number and index modulation
(IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)
A novel transmission scheme is introduced for efficient data transmission by conveying additional information bits through jointly changing the index and number of active subcarriers within each orthogonal frequency division ...
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. ...
