Abstract — In this paper an experimental characterization of a typical indoor wireless propagation channel is performed. This channel characterization is needed for short range applications (<10m), utilizing Ultra-Wideband Impulse Radio (UWB-IR) techniques. Both the line of sight (LOS) and the non line of sight (NLOS) scenarios are taken into account. The characterization is done using time domain measurements of the transmission-reception path, using very short pulses that are propagating through the wireless channel. In order to obtain the channel’s impulse response we utilize the CLEAN algorithm for the time-domain deconvolution technique. The characteristics of the channel that are measured in this study are the path loss, the shadowing effect, the mean excess delay spread, the RMS delay spread and the number of dominant paths
