Abstract:	The location of the mobile station (MS) can be estimated from the distance measures between MS and several base stations (BS). However, the distance measure accuracy is degraded due to the complicated indoor environment, particularly non line-of-sight (NLOS) propagation. In order to improve the accuracy of wireless localization, the knowledge of whether the BS - MS path is line-of-sight (LOS) or NLOS may be of significant importance. Several papers have proposed to use kurtosis for the NLOS.
Abstract:	identification in ultra wide band systems. In this paper, we investigate the kurtosis of the channel impulse response (CIR) and explore the potential of kurtosis for LOS/NLOS identification with different system parameters in terms of both simulations and measurements. The statistical analysis is based on an extensive set MIMO channel measurement data collected at Aalto University. Both simulation and measurement results indicate that kurtosis by using decibel of CIR amplitude provides consistent information about the LOS/NLOS condition regardless of system parameters.
