UW-OCDM for Low-Altitude UAV Communication and Cooperative Sensing
Yi Tao, Zhen Gao, Ziwei Wan +4
Integrated sensing and communications (ISAC) is a key enabler for uncrewed aerial vehicles (UAVs) in the low-altitude economy. This paper proposes an ISAC waveform that embeds a un…
Chirp Delay-Doppler Domain Modulation Based Joint Communication and Radar for Autonomous Vehicles
Zhuoran Li, Zhen Gao, Sheng Chen +3
This paper introduces a sensing-centric joint communication and millimeter-wave radar paradigm to facilitate collaboration among intelligent vehicles. We first propose a chirp wave…
Deep Joint Semantic Coding and Beamforming for Near-Space Airship-Borne Massive MIMO Network
Minghui Wu, Zhen Gao, Zhaocheng Wang +3
Near-space airship-borne communication network is recognized to be an indispensable component of the future integrated ground-air-space network thanks to airships' advantage of lon…
Block-Sparse Tensor Recovery
Liyang Lu, Zhaocheng Wang, Zhen Gao +2
This work explores the fundamental problem of the recoverability of a sparse tensor being reconstructed from its compressed embodiment. We present a generalized model of block-spar…
