A statistical model for the UWB indoor channel

We evaluate a measurement campaign for ultrawideband indoor channels in a typical modern office building. We show that the power delay profile can be well modeled by a single exponential decay with a statistically distributed decay-time constant. We also analyze path loss, amplitude distribution function, and temporal correlation between adjacent multipath components, and give statistical distributions for all those parameters. These results form the basis of a stochastic tapped-delay-line model of the ultra-wideband indoor channel.
