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…
