Enhanced RF Modeling Accuracy Using Simple Minimum Mean-Squared Error Correction Factors

Abstract

This work proposes a quick, accurate means to generate correction factors for established propagation models such as the terrain-integrated rough earth model (TIREM). Minimum Mean-Squared Error (MMSE) techniques are applied, extending the applicability of this already-accurate and flexible propagation model and improving the standard deviation error between measurement and predicted by as much as 6.9 dB in some regions of a signal-strength measurement campaign at the University of Utah campus.
