"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\u202fB 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\u2013100\u202fm ranges. These files serve as the only empirical inputs to Scheme\u202fB and the literature comparison plots."
