Reduced Overhead Channel Estimation for OTFS With Split Pilot
Danilo Lelin Li, Sanoopkumar P. S., Arman Farhang
Orthogonal time frequency space modulation (OTFS) is currently one of the most robust modulation techniques for high Doppler channels. However, to reap the benefits of OTFS, an acc…
Synchronization for Multiuser Uplink OTFS
Mohsen Bayat, Sanoopkumar P. S., Arman Farhang
In this paper, we propose time and frequency synchronization techniques for the uplink of multiuser orthogonal time frequency space (MU-OTFS) in high-mobility scenarios. We introdu…
RIS-Assisted OTFS Communications: Phase Configuration via Received Energy Maximization
Mohamad H. Dinan, Arman Farhang
In this paper, we explore the integration of two revolutionary technologies, reconfigurable intelligent surfaces (RISs) and orthogonal time frequency space (OTFS) modulation, to en…
SC-FDMA as a Delay-Doppler Domain Modulation Technique
Arman Farhang, Mohsen Bayat
This paper compares orthogonal time frequency space (OTFS) modulation and single-carrier frequency division multiple access (SC-FDMA). It shows that these are equivalent except for…
