Times of arrival (TOA) of signals in the Kerr-MOG black hole
General Relativity and Gravitation, 2020 Modified gravity (MOG) theories are alternatives to general relativity (GR) that arose primarily from the need to explain the observed galactic flat rotation curves without invoking the elusive dark matter hypothesized by GR. A well known MOG is the Scalar-Tensor-Vector-Gravity (STVG) developed by Moffat, who has also found a spinning solution called ...

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 ...

A New Time-Based Algorithm for Positioning Mobile Terminals in Wireless Networks
EURASIP Journal on Advances in Signal Processing, 2008 This paper presents a positioning algorithm, named time of arrival to time difference of arrival (TOAD), which computes time-difference-of-arrival (TDOA) measurements from the messages that time-of-arrival (TOA) stations in sight exchange while their ...

Two-Step Time of Arrival Estimation for Pulse-Based Ultra-Wideband Systems
EURASIP Journal on Advances in Signal Processing, 2008 In cooperative localization systems, wireless nodes need to exchange accurate position-related information such as time-of-arrival (TOA) and angle-of-arrival (AOA), in order to obtain accurate location information.

Decawave UWB Clock Drift Correction and Power Self-Calibration
Sensors, 2019 The position accuracy based on Decawave Ultra-Wideband (UWB) is affected mainly by three factors: hardware delays, clock drift, and signal power. This article discusses the last two factors.
