Diffusion-aided Extreme Video Compression with Lightweight Semantics Guidance
Maojun Zhang, Haotian Wu, Richeng Jin +2
Modern video codecs and learning-based approaches struggle for semantic reconstruction at extremely low bit-rates due to reliance on low-level spatiotemporal redundancies. Generati…
Wireless large AI model: shaping the AI-empowered future of 6G and beyond
Fenghao Zhu, Xinquan Wang, Siming Jiang +22
The emergence of sixth-generation and beyond communication systems is expected to fundamentally transform digital experiences through introducing unparalleled levels of intelligenc…
Semantics-Guided Diffusion for Deep Joint Source-Channel Coding in Wireless Image Transmission
Maojun Zhang, Haotian Wu, Guangxu Zhu +3
Joint source-channel coding (JSCC) offers a promising avenue for enhancing transmission efficiency by jointly incorporating source and channel statistics into the system design. A…
Integrated Sensing and Communication in IRS-assisted High-Mobility Systems: Design, Analysis and Optimization
Xingyu Peng, Qin Tao, Xiaoling Hu +3
In this paper, we investigate integrated sensing and communication (ISAC) in high-mobility systems with the aid of an intelligent reflecting surface (IRS). To exploit the benefits…
Beamforming Design for Semantic-Bit Coexisting Communication System
Maojun Zhang, Guangxu Zhu, Richeng Jin +4
Semantic communication (SemCom) is emerging as a key technology for future sixth-generation (6G) systems. Unlike traditional bit-level communication (BitCom), SemCom directly optim…
