Toward Generative Video Communication: A Dual-Stream Digital Transmission Framework
Bingyan Xie, Longyu Zhou, Tianhao Liang +4
Generative video communication has shown promise for bandwidth-constrained wireless transmission and has the potential to support personalized content delivery. In this article, we…
Loss-Resilient Wireless Video Token Communication over Block Fading Channels
Bingyan Xie, Yongjeong Oh, Zihan Chen +3
Video token communication represents video content as discrete tokens that differ in their importance to reconstruction and exhibit temporal dependencies. When these tokens are pac…
Media Meets Communication in 6G: Fundamentals, Key Technologies, and Applications
Bingyan Xie, Longyu Zhou, Zihan Chen +9
The rapid advancement of sixth-generation (6G) networks is accelerating the convergence of media intelligence and communication intelligence, driving media communication beyond con…
On the Gaussian-Quadratic Rate-Distortion Function for Vector Sources with Individual Distortion Constraints
Shuao Chen, Junyuan Gao, Yuxuan Shi +4
This paper investigates the Gaussian-quadratic lossy compression with arbitrary source length under individual distortion constraints. The rate-distortion function (RDF) is lower-b…
Large Language Model-Enhanced Multi-hop Parallel Image Semantic Communication
Bingyan Xie, Jihong Park, Rui Mao +4
This paper proposes a large language model-enhanced multi-hop parallel image semantic communication (LLM-MHPSC) framework to mitigate distortion accumulation in multi-hop wireless…
MD-AirComp+: Adaptive Quantization for Blind Massive Digital Over-the-Air Computation
Li Qiao, Yueqing Wang, Hanjun Jiang +4
Recent research has shown that unsourced massive access (UMA) is naturally well-suited for over-the-air computation (AirComp), as it does not require knowledge of each individual s…
FDD CSI Feedback under Finite Downlink Training: A Rate-Distortion Perspective
Shuao Chen, Junyuan Gao, Yuxuan Shi +4
This paper establishes the theoretical limits of channel state information (CSI) feedback in frequency-division duplexing (FDD) multi-antenna orthogonal frequency-division multiple…
Joint Lossy Compression for a Vector Gaussian Source under Individual Distortion Criteria
Shuao Chen, Junyuan Gao, Yuxuan Shi +4
This paper investigates the joint compression problem of a vector Gaussian source, where an individual distortion constraint is imposed on each source component. It is known that t…
