The major aim of this paper is to present a statistical model for small scale fading and spatial correlation evaluation for indoor UWB channel. A some distributions are suggested for small scale fading statistics where the number of scatterers is unknown. Also, the impact of a number of system parameters on spatial correlation at the receiver is evaluated. The complex correlation coefficient decays slowly with distance under line-of-sight, but decreases quickly under non Line of sight.
