Abstract
We present a statistical model for the characterization of Ultra-Wideband (UWB) channels for outdoor office environment. The bandwidth is from 3-6 GHz and measurements are done for the line-of-sight (LOS) and non-line-of-sight (NLOS) cases. Small scale effects are modeled by the Saleh-Valenzuela (S-V) model with modifications on the ray arrival times and amplitude statistics to fit the empirical data The ray arrival times are to be described by a mixture of Poisson processes while the amplitude statistics are to follow Nakagami distribution with the m parameter following Lognormal distribution. The parameters for the cluster and ray power-decay time constants, cluster and ray arrival times, mean excess delay and RMS excess delay are also extracted to completely define the channel model. © 2005 IEEE.
