Abstract

Frequency domain techniques have been widely used for indoor radio propagation measurements and modeling for telecommunication applications. This paper addresses measurement of the time of arrival (TOA) of the first path for geolocation application using results of frequency domain channel measurements. First, we analyze the effect upon TOA measurement accuracy due to: sampling period of the radio channel in the frequency domain, sampling period in the time domain used for detection of the TOA and the windowing filter used before transformation to time domain. Then we provide some results of measurement in line of sight (LOS) and obstructed LOS (OLOS) indoor environments to compare the characteristics of the measured TOA in these two important scenarios for indoor geolocation applications.
