TDOA Localization in Asynchronous WSNs
2014 12th IEEE International Conference on Embedded and Ubiquitous Computing, 2014This paper proposes a procedure based on time-difference of arrival measurements to localize a blind node in an asynchronous network where a set of nodes with known position is present. The proposed method computes the time-difference of arrival of each transmitted signal to any pair of receiving nodes in order to get rid of the unknown transmission ...

Accurate estimation of time difference of arrival (TDOA) between sensors is a fundamental problem in various applications of sensor networks. In this letter, a novel algorithm is proposed to estimate TDOAs based on low-rank essence of a TDOA matrix, whose entry $(i,j)$ denotes TDOA value between sensors $i$ and $j$ with respect to a ...

TDOA Positioning Based on Factor Graphs
2006 IEEE 17th International Symposium on Personal, Indoor and Mobile Radio Communications, 2006In this paper, we introduce a factor graph based positioning algorithm in wireless cellular networks using time difference of arrival (TDoA) measurements provided by the base stations. The localization process of the mobile station results in a non-linear estimation problem which cannot be solved analytically.

An improved method to sort and pair TDOA based on the correlation between TDOAs
Proceedings of 2011 IEEE CIE International Conference on Radar, 2011In TDOA passive location system, the situations in which false TDOA combinations arose are sorted. For extracting the correct TDOA combination of the radiant source, an improved method to sort and pair TDOA is proposed in this paper. The method can eliminate the false TDOA combinations which are reduced by sub-PRI(pulse repetition interval) of the ...

Influence of Correction for Atmospheric Refraction in passive TDOA location on system TDOA error
2019 International Conference on Control, Automation and Information Sciences (ICCAIS), 2019When radar measures the aerial target, the influence of atmospheric refraction will lead to its measurement error. First, based on the principle of correction for atmospheric refraction on single station system, an algorithm correction for atmospheric refraction of passive TDOA location system is described.

TDOA Localization Scheme with NLOS Mitigation
2020 IEEE 92nd Vehicular Technology Conference (VTC2020-Fall), 2020It is important to deploy the capability to locate a User Equipment (UE) using the Time-Difference-of-Arrival (TDOA) measurements. One of the sources of error is the presence of Non-Line-of-Sight (NLOS) errors in the localization problem, which leads to severe degradation in the localization performance using conventional localization algorithms such ...

Clock Offsets in TDOA Localization
2006Time based TDOA localization systems require time or clock synch-ronization between receivers such as cellular base stations, satellites, and sensor nodes. Imperfection of time synchronization causes degradation in positioning accuracy. However if we know about its characteristics and how to estimate the clock offsets, the localization system can be ...

Multipath detection in TDOA localization scenarios
2012 Workshop on Sensor Data Fusion: Trends, Solutions, Applications (SDF), 2012In this paper, we investigate the detection of multi-path signal propagation in a Time Difference of Arrival (TDOA) localization scenario. Usually, TDOA measurements are obtained by determining the absolute maximum of the cross correlation function of signals recorded at different sensor nodes in a sensor network.

Bounds on Passive Tdoa Estimation in Mixtures
2018 IEEE Statistical Signal Processing Workshop (SSP), 2018We consider the problem of Time Difference of Arrival (TDOA) estimation in mixtures, namely when several sources are received by several receivers, possibly with different delays and attenuations. Under the assumption that the sources are stationary Gaussian with known spectra (a semi-blind scenario), we derive the Cramer-Rao Lower Bound on the Mean ...
