Inter-numerology interference pre-equalization for 5G mixed-numerology communications
(Institute of Electrical and Electronics Engineers Inc., 2022)
This article proposes a pre-equalization method to remove inter-numerology interference (INI) that occurs in multi-numerology OFDM frame structures of fifth-generation New Radio (5G-NR) and beyond, on the transmitter side. ...
IRS-enabled beam-space channel
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2022)
The intelligent reflecting surface (IRS) is emphasized as a controlled scattering cluster. To this end, scatterers and traveling paths of multipath components are classified to build a new channel model. Unlike the ...
A comprehensive experimental emulation for OTFS waveform RF-Impairments
(MDPI, 2023)
The orthogonal time-frequency space (OTFS) waveform exceeds the challenges that face orthogonal frequency division multiplexing (OFDM) in a high-mobility environment with high time-frequency dispersive channels. Since radio ...
Low ICI symbol boundary alignment for 5g numerology design
(Institute of Electrical and Electronics Engineers Inc., 2018)
Symbol boundary alignment, with respect to waveform selection, has an important impact on the numerology design for fifth-generation mobile applications. The current symbol boundary alignment, along with orthogonal frequency ...
Extensionless adaptive transmitter and receiver windowing of beyond 5G frames
(IEEE - Institute of Electrical and Electronics Engineers, Inc, 2020)
Newer cellular communication generations are planned to allow asynchronous transmission of multiple numerologies (waveforms with different parameters) in adjacent bands, creating unavoidable adjacent channel interference. ...
