AbstractWe present results of two indoor ultra-wideband (UWB) channel measurement campaigns in the 2GHz-5GHz frequency band, and use these results to assess the differences and commonalities between UWB channel models and commonly used indoor wideband channel models. We find that the small-scale fading distributions of the UWB channel impulse response taps can still be adequately modeled as complex Gaussian, with a mean component that depends on the measurement setting. The taps are correlated, although the (frequency) diversity order scales linearly with bandwidth. The power-delay profile typically contains several clusters.
