UWB Rectangular Tunnel Modal Path-Loss Modeling Package (Code+Data)

This archive consolidates every asset needed to reproduce the latest UWB rectangular-tunnel study: MATLAB Code: Scripts for modal path-loss simulations, Scheme B calibration, and post-processing of the underground measurements. Running these scripts reproduces figures used in the papers. Processed Measurement Data: Cleaned tunnel datasets with representative points, binned medians, and augmented samples for 0–100 m ranges. These files serve as the only empirical inputs to Scheme B and the literature comparison plots.
