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 ...

An Arctic Sea Ice Energy Budget for the Last Interglacial
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract With ongoing anthropogenic warming, the Arctic is increasingly dominated by thin, first‐year sea ice. Understanding the ice–ocean–atmosphere interactions in warmer climates is therefore essential. We analyze the Arctic sea‐ice energy budget in nine CMIP6‐PMIP4 lig127k simulations of the Last Interglacial warm Arctic.

IEEE Open Journal of Signal ProcessingIn 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

Unveiling the Role of Sea‐Ice Loss in Early‐20th‐Century Arctic Warming
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract Recent Arctic warming and melting sea ice are iconic features of global warming. Yet, it is unlikely that anthropogenic forcing is solely responsible for these changes. The Early‐20th‐Century Arctic Warming (ETCAW), comparable to the recent one, provides a benchmark for natural climate variability but remains poorly understood.

Multi Detector Fusion of Dynamic TOA Estimation using Kalman Filter
, 2015 In this paper, we propose fusion of dynamic TOA (time of arrival) from multiple non-coherent detectors like energy detectors operating at sub-Nyquist rate through Kalman filtering.

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract CMIP6 climate models have difficulties representing the strong absorption properties of biomass‐burning aerosols (BBA) over the Southeast Atlantic and the associated direct forcing. This study takes advantage of unique in situ and remote sensing observations to evaluate the vertical profile and chemical composition of BBA, which are key ...

Distributed Cooperative Localization in Wireless Sensor Networks without NLOS Identification [PDF]
, 2014 In this paper, a 2-stage robust distributed algorithm is proposed for cooperative sensor network localization using time of arrival (TOA) data without identification of non-line of sight (NLOS) links.
