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 nonambiguous 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.
