Journal ArticleDOI
Interference Cancellation and Iterative Detection for Orthogonal Time Frequency Space Modulation
TL;DR: This paper derives the explicit input–output relation describing OTFS modulation and demodulation (mod/demod) and analyzes the cases of ideal pulse-shaping waveforms that satisfy the bi-orthogonality conditions and those which do not.
Journal ArticleDOI
Practical Pulse-Shaping Waveforms for Reduced-Cyclic-Prefix OTFS
TL;DR: The OTFS input–output relation has a simple sparse structure that enables one to use low-complexity detection algorithms and the reduction of out-of-band power may introduce nonuniform channel gains for the transmitted symbols, thus impairing the overall error performance.
Journal ArticleDOI
Embedded Pilot-Aided Channel Estimation for OTFS in Delay–Doppler Channels
P. Raviteja,Khoa T. Phan,Yi Hong +2 more
TL;DR: It is demonstrated that the proposed channel estimation in OTFS significantly outperforms OFDM with known channel information, and extensions of the proposed schemes to multiple-input multiple-output (MIMO) and multi-user uplink/downlink are presented.
Journal ArticleDOI
On Fast-Decodable Space–Time Block Codes
TL;DR: This work derives a novel reduced-complexity 4times2 STBC, and shows that it outperforms all previously known codes with certain constellations.

Flip-OFDM for Unipolar Communication Systems
TL;DR: In this article, the performance and full potential of ACO-OFDM has been investigated in the literature, and a new detection scheme was proposed to reduce the noise at the Flip-OFD receiver by almost 3dB.
