A Simple and Efficient Iterative Method for Toa Localization

IEEE International Conference on Acoustics, Speech, and Signal Processing, 2020
This paper develops a simple and efficient method for source localization using signal time-of-arrival (TOA) measurements. There exist many TOA localization algorithms, most of which require matrix inversions. Their complexity often makes them unsuitable

Scatterer Distribution Based on TOA/AOA and TOA/AOD

Journal of Convergence Information Technology, 2012
Abstract A data driven technique, bivariate kernel density estimator, is used to deduce the scatterer distribution in order to extract the true scatterer distribution in real mobile environment. Under the assumption of single reflection of signal, the TOA /AOA and TOA /AOD measurements are used to obtain the unknown position of the scatterers by means ...

Energy-Based TOA Estimation

IEEE Transactions on Wireless Communications, 2008
This paper investigates time of arrival estimation via impulse radio ultra-wideband technology. A dense multipath channel is assumed and frequency-selective propagation effects are taken into account that make the individual received pulses different in shape from the transmitted monocycles.

A TOA-Based Localization Algorithm With Simultaneous NLOS Mitigation and Synchronization Error Elimination

IEEE Sensors Letters, 2019
Time of arrival (TOA) is one of the most commonly used localization techniques in wireless networks. However, it requires strict time synchronization between source and base stations or anchor nodes, and nonline-of-sight (NLOS) propagation significantly ...

Pulsar navigation using time of arrival (TOA) and time differential TOA (TDTOA)

Acta Astronautica, 2018
Abstract Pulsar navigation is a novel autonomous navigation method for deep-space missions. The pulsar navigation method using the time of arrival (TOA) determines the absolute position of the spacecraft. However, its accuracy is greatly affected by system errors, including the ephemeris error of the pulsar and the satellite-borne clock error.

Combined AOA/TOA UWB localization

2007 International Symposium on Communications and Information Technologies, 2007
In this paper we present a combined angle-of-arrival and time-of-arrival localization scheme, based on two-way range estimation as defined in IEEE 802.15.4a and additional angle estimation, using two closely spaced receiving antennas. Practical measurement results are presented, showing the potential of combined AOA/TOA localization.

Improved Robust TOA-Based Localization via NLOS Balancing Parameter Estimation

IEEE Transactions on Vehicular Technology, 2019
In this paper, the time-of-arrival-based localization problem under mixed line-of-sight/non-line-of-sight (LOS/NLOS) conditions is addressed. Previous studies show that existing robust methods perform well in dense NLOS environments, but generally ...

Comparing Geo-Location Bounds for TOA, TDOA, and Round-Trip Toa

2007 IEEE 18th International Symposium on Personal, Indoor and Mobile Radio Communications, 2007
Development of future geo-location systems requires an understanding of the fundamental limits imposed by system parameters such as bandwidth, SNR, number of sensors, etc. Additionally, the system designer can choose among several existing location techniques, such as time-of-arrival (TOA), time-difference-of-arrival (TDOA), and round-trip time-of ...
