Attenuation Field Prediction Using Physics-Guided Spatio-Temporal Diffusion in LEO Satellite-to-Ground Communications

Accurate attenuation field prediction for low earth orbit satellite-to-ground (StG) is critical for capturing the dynamic variations of signal propagation under complex atmospheric and geometric conditions. Existing StG attenuation modeling implicitly assumes attenuation is a point-wise scalar, which is insufficient fo...
