Experimental characterization of an UWB channel in outdoor environment

An experimental characterization of the ultrawide-band (UWB) channel in an outdoor environment over the frequency range from 3.1 GHz to 5.3 GHz is presented in this paper. The measurements are taken in time domain and line-of-sight (LOS). The statistical model for the delay spread is characterized and there is no correlation between delay spread and transmitter receiver distance. Different statistical distributions for the delay spread are investigated. The reflective nature of this environment is shown in the Ricean K-factor.
