Moyal deformation of the classical arrival time

The quantum time of arrival (TOA) problem requires the statistics of measured arrival times given only the initial state of a particle. Following the standard framework of quantum theory, the problem translates into finding an appropriate quantum image ...

UWB based positioning: Cramer Rao bound for angle of arrival and comparison with time of arrival

, 2006
In this paper we consider the potential of UWB (ultra wide band) signals for positioning. We consider both TOA (time of arrival) and AOA (angle of arrival) based methods. For the AOA method we use a linear array of equi-spaced elements. We derive the CRB

The role of conjugacy in the dynamics of time of arrival operators

The construction of time of arrival (TOA) operators canonically conjugate to the system Hamiltonian entails finding the solution of a specific second-order partial differential equation called the time kernel equation (TKE).

An event qualifier for double differentiator time of arrival estimators

, 1991
A low variance pulse time-of-arrival (TOA) estimator is considered. It should be insensitive to all non TOA parameters and operate without a priori information about any pulse parameters assuming they are constrained to a wide range.

Time-of-Arrival and Angle-of-Arrival Measurement-Assisted 3D Inter-Unmanned Aerial Vehicle Relative Localization Under Distance-Dependent Noise Model

This paper addresses the 3D relative localization problem for two unmanned aerial vehicles (UAVs) using a combination of time-of-arrival (TOA) and angle-of-arrival (AOA) measurements across varied flight trajectories.

Multi-dimensional bounds on time-of-arrival statistics in random scattering channels

, 2011
Bounds on Gaussian and hyperbolic time-of-arrival (ToA) probability density functions (pdfs) in multi-path mobile environments are derived. The bounds are expressed as functions of the coverage distance D between a base station (BS) and a user equipment (
