A deterministic indoor UWB space-variant multipath radio channel modelling compared to measurements on basic configurations

A comparison of measured ultrawideband (UWB) signals and signals simulated by a ray-tracing tool are presented in the paper. The simulation tool is a full 3D indoor deterministic simulator aimed at illustrating low or high bit data rates channel parameters. The physical phenomena intervening in the complex indoor (multipath, shadowing) may be analysed by this means. A measurement campaign aimed at collecting ultrawideband signals in basic transmitter-receiver (Tx-Rx) configurations has been carried out. Simulated and measured signals are thus compared in terms of Impulse Responses and metrics like path losses, energy and delay spread. The work indicates that the deterministic ray-tracing approach can provide useful information for the system designer, especially if it is combined with statistical parameters.
