Interference Mitigation for Time of Arrival Estimation

2010 IEEE Wireless Communication and Networking Conference, 2010
In indoor environments, geolocation using Time of Arrival (TOA) estimation must use a wide bandwidth to overcome the effects of multipath propagation. Narrowband interference from other applications is a significant problem. In this paper we investigate a number of signal processing schemes to detect and overcome one or more relatively narrowband ...

Time of Arrival Statistics in Cellular Environments

2006 IEEE 63rd Vehicular Technology Conference, 2006
In this paper we study the temporal statistics of cellular mobile channel. We propose a scattering model that encloses scatterers in an elliptical scattering disc. We, further, employ this model to derive the probability density function (pdf) of Time of Arrival (ToA) of the multipath signal for picocell, microcell, and macrocell environments.

Time-of-Arrival Measurements

2018
For a radiolocation system the position of an object is determined using some characteristic of the radio frequency signal. These characteristics could include the signal strength, the signal phase (for angle of arrival measurements) or the propagation time-of-flight (TOF) from the transmitter to the receive.

Indoor distance estimation by using time of arrival

2018 26th Signal Processing and Communications Applications Conference (SIU), 2018
Nowadays, researches about indoor positioning is very popular. Estimating location of a communication node can be used in navigation in a shopping mall or tracking in a work place, etc. In applications without a reference point, relative location of the nodes is preferred.

Time-of-arrival photoelectron correlator

Review of Scientific Instruments, 1987
A photoelectron correlator based on the measurement of the joint probability distribution function in the arrival times of eight stop pulses following a single start pulse is described. This correlator has a measurement interval of 5 μs and delay time resolution of 2.5 ns.

Time of Arrival in Quantum Mechanics

Annals of Physics, 1995
Abstract An expression for the quantum time of arrival based on the current density is discussed and justified operationally by means of complex potentials that absorb the incoming wave in a finite distance without reflection or transmission. Previous arguments denying the possibility of defining the time of arrival in quantum mechanics are refuted.

Intelligent time of arrival estimation

2011 IEEE Forum on Integrated and Sustainable Transportation Systems, 2011
Traditional time-of-arrival estimation techniques are often used in advanced transportation systems such as in-car navigation systems and fleet management systems. These techniques tend to neglect certain categories of context when estimating a vehicle's time-of-arrival at a given destination. Particularly important categories of such neglected context
