Handling Uncertainty in Large-Scale Propagation Modelling in Aquatic Environments
Ref: CISTER-TR-250805 Publication Date: 19 to 22, Oct, 2025Abstract:
Accurate channel modelling is essential for enhancing overwater communications in dynamic propagation environments, but it is hindered by variable and noisy measurement data that cause uncertainty in large-scale propagation models. This work examines data uncertainty in overwater shore-to-shore WiFi communications and explores strategies to reduce it. We show that local principal curves allow representing empirical data with lower error than conventional methods. Uncertainty and sensitivity analysis provided insights into regions (water
vs. mud) and periods (rising tide) with high variability in model predictions, and the most influential parameters (antenna heights). Parameter calibration effectively mitigates the impact of input parameter uncertainty.+
