Cramer-Rao bounds in the estimation of time of arrival in fading channels

EURASIP Journal on Advances in Signal Processing, 2018
This paper computes the Cramer-Rao bounds for the time of arrival estimation in a multipath Rice and Rayleigh fading scenario, conditioned to the previous estimation of a set of propagation channels, since these channel estimates (correlation between ...

Moving Target At Constant Velocity Localization Using TOA Measurements From Single Moving Receiver With Unknown Signal Period

IEEE Open Journal of Signal Processing
In this article, we consider using time-of-arrival (TOA) measurements from a single moving receiver to locate a moving target at constant velocity that emits a periodic signal with unknown signal period.

Maximum likelihood localization: When does it fail?

ICT Express, 2016
Maximum likelihood is a criterion often used to derive localization algorithms. In particular, in this paper we focus on a distance-based algorithm for the localization of nodes in static wireless networks. Assuming that Ultra Wide Band (UWB) signals are

Time of arrival extraction for impact localisation on composite structures

Time of arrival (TOA) serves as a widely utilised metric for pinpointing impact locations on composite aircraft structures. Nevertheless, the effectiveness and reliability of existing TOA extraction methods across diverse impact scenarios remains unclear.

Body condition of shorebirds upon arrival at their Siberian breeding grounds [PDF]

, 2009
Arctic breeding shorebirds carry substantial body stores on their long-distance migrations from their non-breeding grounds. Upon arrival at the breeding area the remains of these stores can be used for egg formation, insurance against poor feeding ...
