Abstract :
The propagation of an ultra-wideband (UWB) pulse is simulated in a simplified model of a two-dimensional office environment using the FDTD method. The power delay profile (PDP) is calculated for nine locations. It is found that the PDPs can be characterized using a clustered-exponential decay model. Randomly sized and positioned metal clutter alter the PDPs to follow a single-exponential decay model, with an average decay of -0.50 dB/ns.
