A 3-D Indoor Analysis of Path Loss Modeling Using Kriging Techniques

This study proposes a novel measurement-based method to predict and model three-dimensional (3-D) path loss in indoor scenarios, which first regresses 28 GHz measurements via median modeling then includes ordinary Kriging interpolate shadowing. The performance of this is evaluated by investigating the spatial structure that follows shadowing through semivariogram, covariance function, correlogram as variography tools. It shown semivariogram outperforms other statistics describe continuity terms mean absolute error.
