Abstract: In this paper, we show how current multilateration solutions such as those used in mobile wireless networks can be improved by transforming a TDOA problem into a TOT problem; then solving the problem using a global solution that takes into consideration the UE’s clock bias and UE’s Doppler. We provide new global solutions to the TOT multilateration problem, without requiring an initial position guess. Field results confirm the improvement of the proposed approach of reformulating the TDOA problem as a TOT problem, and substituting Least Squares by Least Absolute Deviations in typical environments with multipath.
