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.

Scatterer Distribution Based on TOA/AOA and TOA/AOD
Journal of Convergence Information Technology, 2012Abstract 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 ...

Comparing Geo-Location Bounds for TOA, TDOA, and Round-Trip Toa
2007 IEEE 18th International Symposium on Personal, Indoor and Mobile Radio Communications, 2007Development 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 ...

Advanced TOA Estimation For Multipath Channels
2020 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2020In this paper, estimation of time of arrival (TOA) in multipath environments is tackled as it is considered a real limiting factor in terrestrial and GNSS positioning systems. Novel methods are presented for designing novel near-causal filters and TOA-Matched Filters (TOA-MF) that facilitate estimation of the TOA. Near and far multipath are effectively

TOA Estimation with the IEEE 802.15.4a Standard
IEEE Transactions on Wireless Communications, 2010This paper discusses a ranging algorithm appropriate for impulse radio ultra-wideband signals compliant with the IEEE 802.15.4a standard. Three steps are indicated to locate the so-called ranging marker in the received signal. The first is to find the highest peaks in the channel responses to the transmitted pulses. The second consists in measuring the

TOA Estimation with Pulses of Unknown Shape
2007 IEEE International Conference on Communications, 2007This 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. Assuming only an approximate knowledge of the received pulses'

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.

TOA Based Joint Synchronization and Localization
2010 IEEE International Conference on Communications, 2010Time of arrival (TOA) based joint synchronization and localization is a very important research area for wireless ad hoc sensor network applications. In this paper we propose a computationally efficient algorithm. The proposed algorithm is based on the linearized equations from TOA measurements, and applies a weighted least square criterion that leads ...
