Identification of Clusters in UWB Channel Modeling

The Saleh-Valenzuela (SV) model is used for modeling UWB propagation by the IEEE 802.15.3a and 802.15.4a standardization groups. A key step for deriving the SV model from the measured channel impulse response is the identification of clusters. In this paper, we propose a method for the non-ambiguous identification of these clusters. Using measured results, we show that the SV parameters obtained using our methodology are consistent for different sets of measurements taken in the same environment.
