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…

Delay-Doppler Multiplexing With Global Filtering
Jialiang Zhu, Mohsen Bayat, Arman Farhang
This paper proposes a novel modulation technique called globally filtered orthogonal time frequency space (GF-OTFS) which integrates single-carrier frequency division multiple acce…
