Non-Orthogonal Time-Frequency Space Modulation
CoRR, 2023 This paper proposes a Time-Frequency Space Transformation (TFST) to derive non-orthogonal bases for modulation techniques over the delay-doppler plane. A family of Overloaded Delay-Doppler Modulation (ODDM) techniques is proposed based on the TFST, which enhances flexibility and efficiency by expressing modulated signals as a linear combination of ...

A Novel ISAC Transmission Framework Based on Spatially-Spread Orthogonal Time Frequency Space Modulation [PDF]
IEEE Journal on Selected Areas in Communications, 2021 In this paper, we propose a novel integrated sensing and communication (ISAC) transmission framework based on the spatially spread orthogonal time frequency space (SS-OTFS) modulation by considering the fact that communication channel strengths cannot be

Super-Orthogonal Block Codes with Multichannel Equalisation and OFDM in Frequency Selective Fading
EURASIP Journal on Wireless Communications and Networking, 2010 Super-orthogonal block codes in space-time domain (i.e., Super-orthogonal space-time trellis codes (SOSTTCs)) were initially designed for frequency nonselective (FNS) channels but in frequency selective (FS) channels these super-orthogonal block codes ...
