Invertible Diffusion for Low-Memory Channel Gain Map Construction in Wireless Communication Networks
Ruifeng Gao, Sen Li, Jue Wang +2
Channel gain maps (CGMs) enable propagation-aware services in edge-intelligent wireless communication networks, while diffusion-based CGM construction is memory intensive for on-de…
A Unified Codebook Design for Curvature-Reconfigurable Apertures: Seamless Near to Far Field Coverage
Zhoujie You, Shu Sun, Ruifeng Gao +2
Beam training for extremely large-scale arrays with curvature-reconfigurable apertures (CuRAs) faces the critical challenge of severe, geometry-dependent angle-range coupling. Whil…
Modeling and Analysis of Land-to-Ship Maritime Wireless Channels at 5.8 GHz
Shu Sun, Yulu Guo, Meixia Tao +6
Maritime channel modeling is crucial for designing robust nearshore communication systems, yet reliable models that account for the dynamic marine environment with varying sea wave…
Maritime Communication in Evaporation Duct Environment with Ship Trajectory Optimization
Ruifeng Gao, Hao Zhang, Jue Wang +5
