Low-Complexity Joint Angle of Arrival and Time of Arrival Estimation of Multipath Signal in UWB System

open access: yesSensors, 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).

Impact of Typhoon Nanmadol (2011) on the propagation of nonlinear internal waves in the South China Sea

open access: yesFrontiers in Marine Science
In situ measurements from an array of pressure-equipped inverted echo sounders (PIESs), numerical simulation results using a non-hydrostatic model (SUNTANS) that does not account for mesoscale variability, and a ray-tracing method are used to investigate

Self-Calibration for the Time Difference of Arrival Positioning

open access: yesSensors, 2020
The time-difference-of-arrival (TDOA) self-calibration is an important topic for many applications, such as indoor navigation. One of the most common methods is to perform nonlinear optimization.

Living with Time: Spirituality and Denis Villeneuve’s Arrival

open access: yesReligions, 2020
At first sight, Denis Villeneuve’s 2016 Arrival seems to provide a fairly standard science fiction narrative about the landing of aliens on earth and the panic that ensues, featuring aggressive soldiers, a suspicious CIA man, brilliant scientists and ...

Quantum arrival time for open systems [PDF]

open access: yesPhysical Review A, 2010
We extend previous work on the arrival time problem in quantum mechanics, in the framework of decoherent histories, to the case of a particle coupled to an environment. The usual arrival time probabilities are related to the probability current, so we explore the properties of the current for general open systems that can be written in terms of a ...
