GLocFM: A Geometry-Aware Foundation Model for 3D Indoor Wireless Localization
Chenghong Bian, Chaozheng Wen, Hongze Chen +1
Learning-based wireless localizers often fail to utilize geometric information about the propagation environment, limiting their ability to exploit non-line-of-sight (NLoS) propaga…
Point2Radio: A Foundation Model for Cross-Scene Radio Fields from Material-Aware Point Clouds
Chaozheng Wen, Chenghong Bian, Hongze Chen +1
High-fidelity radio fields are typically simulated for every scene--transmitter configuration or fitted separately to each scene, failing to exploit propagation structures shared a…
Resolving Multi-Target Association in OFDM-based ISAC via Vision-aided Multi-Modal Learning
Meng Hua, Chenghong Bian, Deniz Gunduz
Orthogonal frequency division multiplexing (OFDM)-based integrated sensing and communication (ISAC) systems commonly extract target parameters by peak-searching a delay-Doppler map…
GeoGS-CE: Learning Delay--Beam Channel Priors with 3D Gaussians for High-Mobility Scenarios
Yumeng Zhang, Jiajia Guo, Chaozheng Wen +2
Wideband channel estimation (CE) in high-mobility scenarios remains challenging because channel responses vary rapidly, while practical systems can allocate only sparse pilots to a…
P-WRFGS: Pruning 3D Gaussians for Efficient Wireless Radiance Field Construction
Chenghong Bian, Meng Hua, Deniz Gunduz
Wireless channel modeling is a key building block for next-generation wireless systems. Predicting the channel state information (CSI) across different transmitter locations can su…
Bridging Visual and Wireless Sensing via a Unified Radiation Field for 3D Radio Map Construction
Chaozheng Wen, Jingwen Tong, Zehong Lin +2
The emerging applications of next-generation wireless networks demand high-fidelity environmental intelligence. 3D radio maps bridge physical environments and electromagnetic propa…
