Model-Consistent Structured-Hankel Matrix Completion for 3D Sparse Multi-frequency Electromagnetic Source Reconstruction
Shujaat Khan, Abdul Wahab
Reconstruction of 3D electromagnetic currents from sparse, multi-frequency, far-field radiation data is severely ill-posed because sparse sampling masks specific current Fourier mo…
PointNeRT: A Physics Aware Neural Ray Tracing Surrogate for Propagation Channel Modeling
Zhuoyin Li, Ruisi He, Mi Yang +5
Ray tracing (RT) has emerged as a key tool for propagation channel modeling and network planning. Conventional RT is based on electromagnetic (EM) wave theory and its application r…
A Multi-Modal Fusion Platform for Joint Environment Sensing and Channel Sounding in Highly Dynamic Scenarios
Xuejian Zhang, Ruisi He, Mi Yang +2
6G system is evolving toward full-spectrum coverage,ultra-wide bandwidth, and high mobility, resulting in increasingly complex propagation environments. The deep integration of com…
Cluster-Based Time-Variant Channel Characterization and Modeling for 5G-Railways
Xuejian Zhang, Ruisi He, Bo Ai +6
With the development of high-speed railways, 5G for Railways (5G-R) is gradually replacing Global System for the Mobile Communications for Railway (GSM-R) worldwide to meet increas…
