A Foundation Model for Cross-Band CSI Reconstruction
Hongpu Zhang, Shu Sun, Ruifeng Gao +2
Acquiring dense high-frequency channel state information (CSI) is costly in multi-band low-altitude wireless systems because pilot resources are limited and channel dimensions chan…
LAMBDA: A Low-Altitude Multimodal Base Dataset for UAV Sensing and Communication
Lin Zhou, Peichuan Rao, Chenshuo Zhang +4
Research on low-altitude integrated sensing and communication (ISAC) requires aligned multimodal data that jointly describe wireless propagation, visual appearance, unmanned aerial…
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…
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
In maritime wireless networks, the evaporation duct effect has been known as a preferable condition for long-range transmissions. However, how to effectively utilize the duct effec…
Directional Measurements and Analysis for FR3 Low-Altitude Channels in a Campus Environment
Yulu Guo, Tongjia Zhang, Xiangwen Gu +3
In this paper, we present detailed low-altitude channel measurements at the FR3 band in an outdoor campus environment. Using a time-domain channel sounder system, we conduct two ty…
