Over-the-air computation (AirComp) has emerged as a promising technology for wireless data aggregation. However, its performance can be severely impaired by unfavorable channel conditions. To address this issue, we investigate AirComp aided by an active reconfigurable intelligent surface (RIS) with a sub-connected arch...

Short-term extreme precipitation nowcasting remains challenging because convective rainfall evolves through coupled moisture, dynamical, and microphysical processes that are only partially observed by any single sensor. Radar composite reflectivity (CR) directly describes hydrometeor structures, whereas global navigati...

This paper studies continuous transmissive reconfigurable intelligent surface (CT-RIS)-enabled multiuser downlink communications, where passive beamforming is characterized by a phase function defined over the continuous aperture. We employ a distance-dependent spherical-wave model for the base station (BS)-to-CT-RIS l...

A tightly-coupled GNSS/inertial navigation system (INS)/Magnetic fusion method based on a kinematics-assisted spatial sequence matching algorithm that effectively suppresses trajectory oscillations and achieves a positioning root mean square error of 2.03 m is proposed.
