The paper describes a new model for the indoor non-line-of-sight (NLOS) UWB channel based on measurements. To date, the Saleh-Valenzuela model (Saleh, A.A. and Valenzuela, R.A., IEEE J. Selected Areas in Commun., vol.SAC-5, no.2, p.128-37, 1987) has been the standard model for indoor NLOS wireless propagation. However, we show that for our set of indoor NLOS UWB channel measurements, better results are obtained using a model which has a fixed number of clusters of multipath arrivals. Our goal is to generate channel models which closely match the statistics of the RMS delay spread, mean excess delay spread, the number of significant multipaths and the RAKE finger energy capture observed in the UWB channel.
