Analysis of Orthogonal Time Frequency Space Transceiver in Baseband Environment

Communications in Computer and Information Science, 2021
In this letter, we investigate Orthogonal Time Frequency Space (OTFS) modulation, a newly proposed modulation scheme for emerging wireless communication applications in time-frequency selective channels, from symbol detection perspective. The studies identify the advantages of OTFS performance over OFDM in many aspects, such as data rate increase in ...

An Orthogonal Time Frequency Space Direct Sequence Modulation Scheme

2021 IEEE International Conference on Communications Workshops (ICC Workshops), 2021
This paper presents an Orthogonal Time Frequency Space Direct Sequence (OTFS-DS) modulation scheme to provide a more robust link. In this scheme, the information symbols are spread in either the delay or Doppler domain by spreading codes. The proposed scheme can gain extra diversity in the delay or Doppler domain as well as full diversity in the time ...

Vehicular Channel Characterization in Orthogonal Time-Frequency Space

2019 IEEE International Conference on Communications Workshops (ICC Workshops), 2019
Orthogonal time-frequency space (OTFS) modulation has been suggested as modulation scheme for the fifth generation of wireless communications and beyond. The scheme is promoted as especially well apt to tackle future challenges of high mobility, millimeter wave communications (mmWave) and massive Multiple-Input Multiple-Output (MIMO).

Orthogonal Time Frequency Space Multiple Access Using Index Modulation

IEEE Transactions on Vehicular Technology, 2023
Orthogonal time frequency space (OTFS) is a recent two-dimensional modulation technique utilizing delay-Doppler domain and nominated as a promising candidate waveform for beyond 5G communication systems. By leveraging both time and frequency selectivity of doubly-dispersive radio channels, it has shown a better performance compared to traditional ...

Variational autoencoder based receiver for orthogonal time frequency space modulation

Digital Signal Processing, 2021
Abstract The emerging orthogonal time frequency space (OTFS) modulation is demonstrated to offer reliable communication performance advantages over orthogonal frequency division multiplexing (OFDM) in doubly-dispersive fading channel. However, the existing embedded pilot-aided method to estimate channel impulse response (CIR) requires enormous ...
