Tube-Structured Incremental Semantic HARQ for Generative Video Receivers
Xuesong Wang, Xinyan Xie, Runxin Zhang
Generative semantic communication uses receiver-side generative priors to reconstruct visual content from compact semantics, making it attractive for bandwidth-limited multimedia d…
Revisiting the Independence Assumption in LEO Satellite-to-Ground Optical Links: A State-Coupled Joint Fading Model
Xinyan Xie, Xuesong Wang, Jinghua Zhang +4
Performance analysis of low Earth orbit (LEO) satellite-to-ground optical links relies on composite fading models that typically evaluate scintillation and angular loss under the a…
Diffusion-Aided Bandwidth-Efficient Semantic Communication with Adaptive Requests
Xuesong Wang, Xinyan Xie, Mo Li +1
Semantic communication focuses on conveying the task-relevant meaning rather than exact bitwise recovery. For image transmission with a generative receiver, relying only on text de…
Adaptive Lighting Control in Visible Light Systems: An Integrated Sensing, Communication, and Illumination Framework
Xinyan Xie, Xuesong Wang, Xin Lai +5
Indoor visible light communication (VLC) is a promising sixth-generation (6G) technology, as its directional and sensitive optical signals are naturally suited for integrated sensi…
