Abstract
Statistical modeling of Ultra-Wideband (UWB) signals is undertaken to examine the existence of short term fading and shadowing. Based on the data collected from multiple locations and 4 different sites using a single transmitter and a 96-element receiving antenna in the 2-8 GHz range, hypothesis testing was performed to explore the statistical fit to composite probability density functions such as the double Rayleigh, double Nakagami and the K distribution as well as the Nakagami and lognormal. The tests clearly showed that excellent match existed with the K distribution, with the Nakagami distribution being the next best. The results point to the existence of shadowing besides the short fading reported by other researchers and will assist in the development of fading and shadowing mitigation techniques.Citation
