RoboLoc: A Benchmark Dataset for Point Place Recognition and Localization in Indoor–Outdoor Integrated Environments

IET Image Processing, Volume 20, Issue 1, January/December 2026.
RoboLoc is a new benchmark dataset designed for GPS‐free point place recognition in environments with indoor–outdoor transitions and floor changes. It includes real‐world robot trajectories with diverse elevation and domain conditions, addressing the limitations of existing LiDAR datasets.

Physical Parameters Estimation Using Roadside Monocular Vision

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper proposes a new monocular vision‐based roadside perception and measurement method, which combines deep learning‐based target detection algorithms and coordinate transformation methods to measure different kinds of physical parameters of the targets and give GPS information under the global navigation satellite system, in order to meet the ...

Dynamically configurable architectures for multi-GNSS receiver

, 2017
This dissertation has focused on the development of dynamically configurable and programmable architectures for multi-GNSS receivers. The effect of RF front-end architecture and new characteristics of GNSS signals (modulation type, primary code generation, secondary code, required bandwidth and sampling frequency) on the complexity of the baseband ...

WFH: A Wideband Frequency Hopping‐Based Anti‐Jamming Navigation Signal Structure

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
Given the limitations of existing satellite navigation signals in antijamming performance amid growing environmental jamming, this paper proposes a navigation signal structure based on wideband frequency hopping (WFH) modulation to enhance both antijamming capability and measurement accuracy. It further introduces the nonstationary effective carrier‐to‐
