Times of arrival (TOA) of signals in the Kerr-MOG black hole

General Relativity and Gravitation, 2020
This paper studies the effect of frame dragging on the difference of times of arrival of signals coming from a variable pulsar and passing nearby a rotating black hole in the scalar-tensor-vector-gravity alternative theory due to Moffat. It may be used to constrain an additional parameter that theory contains with respect to ordinary general relativity.

Pulsar navigation using time of arrival (TOA) and time differential TOA (TDTOA)

Acta Astronautica, 2018
Abstract Pulsar navigation is a novel autonomous navigation method for deep-space missions. The pulsar navigation method using the time of arrival (TOA) determines the absolute position of the spacecraft. However, its accuracy is greatly affected by system errors, including the ephemeris error of the pulsar and the satellite-borne clock error.

Estimation of Channel State Information (CSI) in Cell-Free Massive MIMO Based on Time of Arrival (ToA)

Wireless Personal Communications, 2020
Cell-free massive multiple input multiple output (MIMO) comprises a large number of distributed single antenna access points (APs) connected to a network controller through backhaul. Each user is served by neighbouring APs simultaneously. Cell-free Massive MIMO provides decent throughput and coverage improvement as compared to a small-cell.

Improvement in estimation of time of arrival (TOA) from timing advance (TA)

ICUPC '98. IEEE 1998 International Conference on Universal Personal Communications. Conference Proceedings (Cat. No.98TH8384), 2002
Wireless systems reporting TOA (time of arrival), the propagation time from the mobile station (MS) to the base station (BS), may use this information to assist with automatic location identification (ALI). The TA (timing advance), used in TDMA systems, may be used as an approximation for TOA.

Simulation of Lightning Flash in Time of Arrival (TOA) Method by Using Three Broadband Antennas

2011 UKSim 5th European Symposium on Computer Modeling and Simulation, 2011
Various methods are used to locate cloud-to-ground lightning flash. The accuracy of the methods depends on the number of sensor stations, station topology, mathematical model adopted for the analyses, and type of measuring equipment. For a single station with the configuration of short baseline in a measuring system, the accuracy analysis is mostly ...

Time-of-arrival (TOA) estimation based structured sparse channel estimation algorithm, with applications to digital TV receivers

2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2004
We introduce a new structured channel impulse response (CIR) estimation method for sparse multipath channels where we demonstrate a robust way of restoring the pulse shape into the composite CIR. We call this novel CIR estimation method time-of-arrival based blended least squares (TOA-BLS) which uses symbol rate sampled signals, and it is based on ...

CME-learn: An interactive playground to benchmark CME databases for the time of arrival (ToA) prediction for using machine learning methods.

2022
<p>Coronal mass ejections are one of the most significant drivers of space weather. The ToA predictions along with the Arrival speed of the CMEs are one of the crucial pieces of information for preparing for the possible geomagnetic storms.

A Novel Pilot Aided Time of Arrival (TOA) Estimation Algorithm for Vehicular OFDM Systems in Specular Wireless Channels

2008 IEEE Globecom Workshops, 2008
Channel estimation is vital for implementing schemes such as coherent detection and adaptive bit loading, which make OFDM an attractive PHY layer technology for vehicular wireless communications. However, knowledge of the exact time of arrival (TOA) information of the multi-path components of the vehicular wireless channel is required to achieve ...
