In this work, to address the challenge of joint channel estimation and data detection (JED) for orthogonal delay-Doppler (DD) division multiplexing (ODDM) in doubly selective chann…
A Novel ISAC Waveform Based on Orthogonal Delay-Doppler Division Multiplexing with FMCW
Kehan Huang, Akram Shafie, Min Qiu +2
In this work, we propose the orthogonal delay-Doppler (DD) division multiplexing (ODDM) modulation with frequency modulated continuous wave (FMCW) (ODDM-FMCW) waveform to enable in…
Achieving Full Multipath Diversity by Random Constellation Rotation: a Theoretical Perspective
Xuehan Wang, Jinhong Yuan, Jintao Wang +1
Diversity is an essential concept associated with communication reliability in multipath channels since it determines the slope of bit error rate performance in the medium to high…
Orthogonal Delay-Doppler Division Multiplexing Modulation with Hierarchical Mode-Based Index Modulation
Kehan Huang, Min Qiu, Jinhong Yuan
The orthogonal time frequency space with index modulation (OTFS-IM) offers flexible tradeoffs between spectral efficiency (SE) and bit error rate (BER) in doubly selective fading c…
Performance of orthogonal delay-doppler division multiplexing modulation with imperfect channel estimation
Kehan Huang, Min Qiu, Jun Tong +2
The orthogonal delay-Doppler division multiplexing (ODDM) modulation is a recently proposed multi-carrier modulation that features a realizable pulse orthogonal with respect to the…
