OAMP-Aided Joint Channel Estimation and Data Detection for ODDM Systems
Kehan Huang, Min Qiu, Akram Shafie +1
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…
Design of APSK Constellations Approaching the Communication-Sensing Pareto Boundary for ISAC
Yujie Shao, Min Qiu, Ming-Chun Lee +2
We propose a semi-analytical design framework for amplitude phase shift keying (APSK) signaling for integrated sensing and communication (ISAC), focusing on i.i.d. uniform discrete…
Channel Estimation with Hierarchical Sparse Bayesian Learning for ODDM Systems
Jiasong Han, Xuehan Wang, Jingbo Tan +4
Orthogonal delay-Doppler division multiplexing (ODDM) is a promising modulation technique for reliable communications in high-mobility scenarios. However, the existing channel esti…
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…
Half Spatially Coupled Turbo-Like Codes
Xiaowei Wu, Lei Yang, Min Qiu +2
This paper presents a new class of spatially coupled turbo-like codes (SC-TCs), namely half spatially coupled braided convolutional codes (HSC-BCCs) and half spatially coupled para…
