Robust and Secure Near-Field Communication via Curved Caustic Beams
Shicong Liu, Xianghao Yu, Robert Schober
Near-field beamfocusing with extremely large aperture arrays can effectively enhance physical layer security. Nevertheless, even small estimation errors of the eavesdropper's locat…
MIMO Beam Map Reconstruction via Toeplitz-Structured Matrix-Vector Tensor Decomposition
Hao Sun, Junting Chen, Xianghao Yu
As wireless networks progress toward sixthgeneration (6G), understanding the spatial distribution of directional beam coverage becomes increasingly important for beam management an…
Structure-Aware Near-Field Radio Map Recovery via RBF-Assisted Matrix Completion
Hao Sun, Xianghao Yu, Junting Chen
This paper proposes a novel structure-aware matrix completion framework assisted by radial basis function (RBF) interpolation for near-field radio map construction in extremely lar…
Flow Matching-Based Active Learning for Radio Map Construction with Low-Altitude UAVs
Hao Sun, Shicong Liu, Xianghao Yu +1
The employment of unmanned aerial vehicles (UAVs) in the lowaltitude economy necessitates precise and real-time radio maps for reliable communication and safe navigation. However,…
A Support Vector Approach in Segmented Regression for Map-assisted Non-cooperative Source Localization
Hao Sun, Weiming Huang, Xianghao Yu +1
This paper presents a non-cooperative source localization approach based on received signal strength (RSS) and 2D environment map, considering both line-of-sight (LOS) and non-line…
