Low Complexity Detection of Spatial Modulation Aided OTFS in Doubly-Selective Channels
IEEE Transactions on Vehicular Technology, 2023 A spatial modulation-aided orthogonal time frequency space (SM-OTFS) scheme is proposed for high-Doppler scenarios, which relies on a low-complexity distance-based detection algorithm.

OTFS Modulation with Phase Noise in mmWave Communications
2019 IEEE 89th Vehicular Technology Conference (VTC2019-Spring), 2019Orthogonal time frequency space modulation (OTFS) modulation is a 2-dimensional modulation technique designed in delay-Doppler domain, suited for doubly dispersive wireless channels. OTFS modulation has been shown to achieve superior error performance compared to the conventional multi-carrier systems.

BER Performance Analysis for NOMA Systems with OTFS Modulation
2023 31st Signal Processing and Communications Applications Conference (SIU), 2023This study examines the non-orthogonal multiple access (NOMA) system that is modulated with orthogonal time-frequency-space (OTFS), which is a potential waveform candidate that is frequently used in sixth-generation (6G) wireless communication networks and is shown to improve performance in high mobility scenarios.

Performance Analysis of OTFS Modulation with Transmit Antenna Selection
2021 IEEE 93rd Vehicular Technology Conference (VTC2021-Spring), 2021In this paper, we consider transmit antenna selection (TAS) in orthogonal time frequency space (OTFS) modulation and analyze its performance. We assume that the channel is quasi-static in the delay-Doppler (DD) domain and there is limited feedback from the receiver to the transmitter.
