Low-Complexity Linear Equalization for OTFS Modulation
IEEE Communications Letters, 2020In this letter, we propose low-complexity linear equalizers for orthogonal time frequency space (OTFS) modulation that exploit the structure of the effective channel matrix in OTFS. The proposed approach exploits the block circulant nature of the OTFS channel matrix to achieve significant complexity reduction.

Spatial Modulation Based MIMO-OTFS Transmissions
2021 IEEE/CIC International Conference on Communications in China (ICCC Workshops), 2021Orthogonal time frequency space (OTFS) is a novel modulation scheme designed in delay-Doppler domain, which shows a strong Doppler-resilience over doubly-dispersive channels. The interaction between delay-Doppler channel and OTFS symbols allows a linear scaling of capacity with the multiple-input multiple-output (MIMO) order and simultaneously enables ...

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.
