Waveform-domain NOMA: An Enabler for ISAC in Uplink Transmission
Jialiang Zhu, Hamza Haif, Abdelali Arous +2
According to the recent 3GPP decisions on 6G air interface, orthogonal frequency-division multiplexing (OFDM)-based waveforms are the primary candidates for future integrated sensi…
A Unified Framework for Adaptive Waveform Processing in Next Generation Wireless Networks
Abdelali Arous, Hamza Haif, Arman Farhang +1
The emergence of alternative multiplexing domains to the time-frequency domains, e.g., the delay-Doppler and chirp domains, offers a promising approach for addressing the challenge…
Time and Frequency Synchronization for Multiuser OTFS in Uplink
Mohsen Bayat, Sanoopkumar P. S., Arman Farhang
In this paper, we propose time and frequency synchronization techniques for uplink multiuser OTFS (MU-OTFS) systems in high-mobility scenarios. This work focuses on accurately esti…
PAPR of DFT-s-OTFS with Pulse Shaping
Jialiang Zhu, Sanoopkumar P. S., Arman Farhang
Orthogonal Time Frequency Space (OTFS) suffers from high peak-to-average power ratio (PAPR) when the number of Doppler bins is large. To address this issue, a discrete Fourier tran…
Time Frequency Localized Pulse for Delay Doppler Domain Data Transmission
Sanoopkumar P. S, Muyiwa Balogun, Liam Barry +1
Orthogonal time frequency space (OTFS) is a strong candidate waveform for sixth generation wireless communication networks (6G), which can effectively handle time varying wireless…
