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 ...

Distributed Tdoa-Based Indoor Source Localisation
2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2018Indoor localisation is an important research topic with several possible applications. For example, knowing a user's location can be used as navigation aid in hospitals and malls, or for better targeted marketing. In this paper we consider the case where the environment of interest is equipped with several receivers (with known location) from which ...

The majority principle in TDOA estimation
2010 8th International Conference on Communications, 2010The 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 ...

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.

Position Estimation Using UWB TDOA Measurements
2006 IEEE International Conference on Ultra-Wideband, 2006UWB signal has high ranging precision due to its large bandwidth. In this paper, TDOA ranges measured by UWB signals are used in the position estimation process. The ranges are modeled for both LOS and NLOS environment. A TDOA error-minimizing localization method has been proposed to estimate the locations of blind nodes and its performance is ...

Cooperative Estimation Algorithms Using TDOA Measurements
2007A navigation algorithm using Time Difference of Arrival (TDOA) measurements obtained from signals of opportunity (SOPs) is developed. SOP-derived TDOA measurements are signals that are transmitted for purposes other than navigation (such as communication, telecasts, etc.) and are motived as appealling alternatives to GPS.

Cross-spectral TDOA and FDOA estimation
SPIE Proceedings, 2014We present methods for accurately estimating and tracking instantaneous frequency and relative time delay of narrowband signal components. These methods are applied to the problem of estimating the location of an emitter from the signal(s) received by one or more receivers.
