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.

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.

Fusion Localization Algorithm Based on Robust IMM Model Combined with Semi-Definite Programming

Actuators, 2022
With the continuous development of wireless sensor network (WSN) technology, WSN has gradually become one of the key technologies of the Internet, and is widely used in indoor target location technology. However, the obstacles will have a great influence

Time-of-Arrival States [PDF]

, 1998
Although one can show formally that a time-of-arrival operator cannot exist, one can modify the low momentum behaviour of the operator slightly so that it is self-adjoint.

Time-of-arrival in quantum mechanics [PDF]

, 1996
We study the problem of computing the probability for the time-of-arrival of a quantum particle at a given spatial position. We consider a solution to this problem based on the spectral decomposition of the particle's (Heisenberg) state into the ...

A Fractional Programming Method for Target Localization in Asynchronous Networks

IEEE Access, 2018
In this paper, we address the target device localization problem in the asynchronous networks. For the purpose of saving power resources, the target device is not synchronized with the anchor nodes, but is only required to listen to the signals ...

Weak measurement of arrival time [PDF]

, 2002
The arrival time probability distribution is defined by analogy with the classical mechanics. The difficulty of requirement to have the values of non-commuting operators is circumvented using the concept of weak measurements.
