Abstract

The author deals in the paper with simulations of stochastic EM fields dedicated especially to 5G frequency band for which FDTD calculation domain becomes relatively large. The PCE-based FDTD is considered in the paper. The author presents an approach for a relatively very fast calculation of PCE coefficients for the case when multiple FDTD simulations of a considered wireless scenario are required. This is the case when more than one set of probability densities of the scenario parameters need to be considered, e.g. different nominal (mean) positions of antenna and/or obstacles. The author proposes also a concept for an improvement of a PCE-FDTD code which provides a substantial decrease of a simulation time.
