TOA measurement processing analysis for positioning in NLOS conditions

In this paper we present the analysis of time of arrival (TOA) analytical positioning algorithms in mobile communication networks, as well as the dependence of positioning accuracy on the number of sources with non-line-of-sight (NLOS). Proposed simulation model established sufficient number of base stations for correct mobile position estimation that provides computational complexity reduction. Taking into consideration statistical estimation theory obtained results and correlations of root mean square error (RMSE) were confirmed by Cramer-Rao bound.
