Low-Complexity Joint Angle of Arrival and Time of Arrival Estimation of Multipath Signal in UWB System [PDF]
Sensors, 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).

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 ...

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 ...

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.

Semidefinite Programming Algorithms for 3-D AOA-Based Hybrid Localization
IEEE Open Journal of Signal Processing, 2023 By taking different kinds of measurements at the same time, it may be possible to improve the accuracy of target localization or reduce the number of sensors needed.

Differentiability of the Arrival Time [PDF]
Communications on Pure and Applied Mathematics, 2016 AbstractFor a monotonically advancing front, the arrival time is the time when the front reaches a given point. We show that it is twice differentiable everywhere with uniformly bounded second derivative. It is smooth away from the critical points where the equation is degenerate.
