Optimal estimation of TOA in the TDOA problem

2013 Australian Communications Theory Workshop (AusCTW), 2013
In the time difference of arrival (TDOA) problem, the unknown location of an emitter is estimated using a set of TDOA estimates. In this paper, a closed-form solution for a nominal TOA in the TDOA problem is presented for the case of three or four receivers that under certain conditions results in location estimates that are optimal in the least-square

Positioning Algorithms for Cellular Networks Using TDOA

2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006
In this paper, we investigate the performance of positioning algorithms in wireless cellular networks based on time difference of arrival (TDoA) measurements provided by the base stations. The localization process of the mobile station results in a non-linear least squares estimation problem which cannot be solved analytically.

Comments on "Analysis of geolocation by TDOA"

IEEE Transactions on Aerospace and Electronic Systems, 1995
Ho, K.C., and Chan, Y.T. (1993) give an alternative solution algorithm for the time difference of arrival (TDOA) problem. The commenter suggests that a number of claims presented in this article are unjustified. He also presents corrections of what he suggests are errors. In their reply, the authors explain their claims. >

The measurement of TDOA short baseline

International Conference on Military Technologies (ICMT) 2015, 2015
The main aim of this work was to measure, verify and evaluate accuracy of target-location estimation in time difference of arrival (TDOA) method. Measuring workplace for TDOA measurement was assembled by using three receiving antennas, their distances were around 15 m each.

The majority principle in TDOA estimation

2010 8th International Conference on Communications, 2010
The time difference of arrival (TDOA) estimation as a particular time delay estimation (TDE) problem has many practical applications. One of them refers to leak detection and localization in fluid pipelines. This paper introduces the majority principle as a method to increase the probability of a correct localization of the leak, with important ...
