A Fast Location Algorithm Based on TDOA
Proceedings of the 4th International Conference on Control, Mechatronics and Automation, 2016This paper presents a new algorithmbasedon TDOA to get the sound sourceposition, which can be applied to indoor positioning, underwater navigation, radar searching, etc. The unknown of the range is extracted only from the equations and estimated firstly in thealgorithm.

Cooperative TDOA estimation with trigger relay
2011 IEEE 22nd International Symposium on Personal, Indoor and Mobile Radio Communications, 2011In this paper, we investigate the relaying issue of Zero-Padding (ZP) Orthogonal Frequency Division Multiplexing (OFDM) technique to estimate Time Difference of Arrival (TDOA) for locationing applications. In order to benefit from the easy processing of Amplify-and-Forward (AF) relay as well as the noise and interference cancellation of Decode-and ...

Unsynchronized ultrasound system for TDOA localization
2014 International Conference on Indoor Positioning and Indoor Navigation (IPIN), 2014Indoor localization based on time difference of arrival (TDOA) has been recently a promising field of study. We consider the previously unsolved problem of locating a moving target receiver by using unsynchronized stationary beacons without requirement of manual calibration. Thus, the received signals and their time of arrival (TOA) have to be assigned

PRZEGLĄD TELEKOMUNIKACYJNY - WIADOMOŚCI TELEKOMUNIKACYJNE, 2015
Przedstawiono nową metode lokalizowania terminali ruchomych MT (Mobile Terminal) w sieciach radiowych, w ktorych stacje bazowe BS (Base Station) pracują asynchronicznie wzgledem siebie. Metoda ta, nazwana ATDOA (Asynchronous Time Difference of Arrival), umozliwia estymacje polozenia MT na podstawie pomiarow roznicy czasow propagacji sygnalow radiowych ...

Anchor-free TDOA self-localization
2011 International Conference on Indoor Positioning and Indoor Navigation, 2011We present an approach for the localization of passive receiver nodes in a communication network. In our settings the positions of the nodes are unknown. The only source of information is the time when environmental sound or ultrasound signals are received. The discrete signals occur at unknown positions and times, but they can be distinguished.

NLOS Mitigation Method for TDOA Measurement
2010 Sixth International Conference on Intelligent Information Hiding and Multimedia Signal Processing, 2010In this paper, a non-line-of-sight (NLOS) error mitigation on time-difference-of-arrival (TDOA) measurements from pilot signals of a wireless communication network is proposed to solve the positioning and tracking issue involved in the environments where some base stations have NLOS errors.

TDOA assisted RSSD localization in UWB
2012 9th Workshop on Positioning, Navigation and Communication, 2012This paper considers ultra-wideband (UWB) based localization of mobile users in indoor environment. Because of severe multipath indoor localization still presents a challenging issue and UWB is often considered as technology enabling precise localization.

On the applicability of the residual weighting algorithm for TDOA
2012 IV International Congress on Ultra Modern Telecommunications and Control Systems, 2012Locating a mobile transmitter passively is a challenging task. Recently, the most preferred method for this matter is the Time Difference of Arrival (TDOA) method. In this paper, different techniques for enhancing the TDOA results are introduced. They generally give an idea about the challenges of TDOA.

A hybrid TDoA-ToA localization method
ICT 2013, 2013One of the main advantages when comparing time over signal strength localization methods, is that the former do not require the creation of fingerprint databases. On the other hand, the majority of time based methods require some sort of clock synchronization due to the drifting of the local clocks.
