Time and Frequency Synchronization for OTFS
IEEE Wireless Communications Letters, 2022 In this paper, we propose timing offset (TO) and carrier frequency offset (CFO) estimators for orthogonal time frequency space modulation (OTFS). The proposed estimators do not require any additional training overheads as they deploy the same pilot signal that is used for channel estimation.
