Time of arrival from Bohmian flow [PDF]
Journal of Physics A: Mathematical and General, 2002 We develop a new conception for the quantum mechanical arrival time distribution from the perspective of Bohmian mechanics. A detection probability for detectors sensitive to quite arbitrary spacetime domains is formulated. Basic positivity and monotonicity properties are established.

A Novel Method for Asynchronous Time-of-Arrival-Based Source Localization: Algorithms, Performance and Complexity. [PDF]
Sensors (Basel), 2020 In time-of-arrival (TOA)-based source localization, accurate positioning can be achieved only when the correct signal propagation time between the source and the sensors is obtained. In practice, a clock error usually exists between the nodes causing the

Confined Quantum Time of Arrivals [PDF]
Physical Review Letters, 2004 We show that formulating the quantum time of arrival problem in a segment of the real line suggests rephrasing the quantum time of arrival problem to finding states that evolve to unitarily collapse at a given point at a definite time. For the spatially confined particle, we show that the problem admits a solution in the form of an eigenvalue problem ...

Low-Complexity Joint Angle of Arrival and Time of Arrival Estimation of Multipath Signal in UWB System. [PDF]
Sensors (Basel), 2023 In an ultra-wideband (UWB) system, the two-dimensional (2D) multiple signal classification (MUSIC) algorithms based on high-precision 2D spectral peak search can jointly estimate the time of arrival (TOA) and angle of arrival (AOA).

Inertial and time-of-arrival ranging sensor fusion. [PDF]
Gait Posture, 2017 Wearable devices with embedded kinematic sensors including triaxial accelerometers, gyroscopes, and magnetometers are becoming widely used in applications for tracking human movement in domains that include sports, motion gaming, medicine, and wellness. The kinematic sensors can be used to estimate orientation, but can only estimate changes in position

IEEE 802.15.4 ZigBee-Based Time-of-Arrival Estimation for Wireless Sensor Networks. [PDF]
Sensors (Basel), 2016 Precise time-of-arrival (TOA) estimation is one of the most important techniques in RF-based positioning systems that use wireless sensor networks (WSNs).

Times of arrival and gauge invariance [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2021 We revisit the arguments underlying two well-known arrival-time distributions in quantum mechanics, viz., the Aharonov–Bohm–Kijowski (ABK) distribution, applicable for freely moving particles, and the quantum flux (QF) distribution. An inconsistency in the original axiomatic derivation of Kijowski’s result is pointed out, along with an inescapable ...

Low-Complexity Wideband Interference Mitigation for UWB ToA Estimation
Sensors, 2023 Reliable time of arrival (ToA) estimation in dense multipath (DM) environments is a difficult task, especially when strong interference is present. The increasing number of multiple services in a shared spectrum comes with the demand for interference ...

Robust localization in wireless networks from corrupted signals
EURASIP Journal on Advances in Signal Processing, 2021 We address the problem of timing-based localization in wireless networks, when an unknown fraction of data is corrupted by non-ideal propagation conditions.
