Analysis of kurtosis-based LOS/NLOS identification using indoor MIMO channel measurement

The positioning methods based on the received signal strength (RSS) measurement connect the RSS value with location of the mobile station (MS). However, the accuracy of location is degraded due to the complicated indoor environment, particularly no-line-of-sight (NLOS) propagation. In order to improve the accuracy and reliability of wireless location, the knowledge of whether the base station (BS)-MS path is line-of-sight (LOS) or NLOS is very important. In this paper, we present statistics analysis based on multiple-input and multiple-output (MIMO) channel measurement to perform NLOS identification.Peer reviewe
