Spatial behavior of UWB channel pertinent to indoor geolocation

Description

This item was taken from the IEEE Conference ' Spatial behavior of UWB channel pertinent to indoor geolocation ' This paper describes the results of frequency-domain dynamic channel sounding in a typical office environment for studying the spatio-temporal channel behavior pertinent to indoor geolocation. It consists of detailed characterization of complex frequency responses of ultra-wideband (UWB) signals having a nominal center frequency of 5.5GHz and bandwidth of 5GHz. The effects of distance, threshold for picking paths, bandwidth, and occurrence of none-line-of-sight (NLOS) on multipath parameters such as number of multipath-components (MPCs) and path persistency are presented. Furthermore, a novel model for the dynamic behavior of number of MPCs is proposed.
