This paper investgates a unmanned aerial vehicle‐assisted non‐orthogonal multiple access‐integrated sensing and communication system, which fuses the UAV's echo signal and target position by employing the extended Kalman filter algorithum to achieve high‐precision prediction of the target trajectory.

Collaborative Beamforming for Multi‐Target Localization Using Passive Anchors
A joint collaborative beamforming strategy for passive sensor network is proposed active sensors generate collaborative beam to power up the passive sensors and attain accurate self‐localization. ABSTRACT Using wireless passive sensor nodes as anchors is a cost‐effective way for localization system.

Robust Beamforming for ISAC Systems via Probability of Detection Optimisation
We propose a two‐step robust beamforming design for ISAC that maximises multi‐target detection probability while satisfying multi‐user SINR and per‐antenna power constraints. A sensing‐only Riemannian optimisation on the oblique manifold shapes the transmit covariance, followed by SDR‐based reconstruction to enforce communication guarantees ...

A Voronoi Diagram‐Based Approach for AC Optimal Power Flow
This paper presents a new approach for AC optimal power flow. The proposed approach begins by constructing a Voronoi diagram using a set of initial sample points that represent candidate solutions distributed across the search space. It then iteratively adds new sample points, including: (i) a tentative optimal point obtained via the continuous ...

Formation control of multi‐autonomous underwater vehicle (AUV) systems is essential for collaborative ocean tasks such as environmental monitoring and resource exploration, but it is hindered by challenges like limited flexibility in formation transformation, model uncertainties, and unknown ocean current disturbances.

An Iterative Method for Moving Target Localization Using TDOA and FDOA Measurements
For moving targets localization, incorporating frequency-difference-of-arrival (FDOA) measurements in the commonly used time-difference-of-arrival (TDOA) positioning systems will improve performance.

Robust Widely Linear Beamforming With Multiple Uncertainty Sets
The widely linear minimum variance distortionless response (WL-MVDR) beamformer has a better performance than the conventional MVDR beamformer when the received signals are potentially noncircular. However, it is sensitive to the extended steering vector

Direct Data‐Driven State‐Feedback Control of Linear Parameter‐Varying Systems
ABSTRACT The framework of linear parameter‐varying (LPV) systems has shown to be a powerful tool for the design of controllers for complex nonlinear systems using linear tools. In this work, we derive novel methods that allow us to synthesize LPV state‐feedback controllers directly from only a single sequence of data and guarantee stability and ...

One‐Shot Method for Computing Generalized Winding Numbers
Abstract The generalized winding number is an essential part of the geometry processing toolkit, allowing to quantify how much a given point is inside a surface, even when the surface has boundaries and noise. We propose a new universal method to compute a generalized winding number, based only on the surface boundary and the intersections of a single ...
