RFDT-Channel: RGB-LiDAR-Based RF Digital Twin Scene Construction for 28 GHz Indoor Ray-Tracing Channel Simulation
Chengyang Yao, Cunhua Pan, Jiaming Zeng +5
Real-scene indoor millimeter-wave simulation requires efficient modeling of radio frequency (RF)-computable geometry and electromagnetic material properties. To address the low eff…
A BEV-Fusion Based Framework for Sequential Multi-Modal Beam Prediction in mmWave Systems
Jiaming Zeng, Cunhua Pan, Haoyang Weng +3
Beam prediction is critical for reducing beam-training overhead in millimeter-wave (mmWave) systems, especially in high-mobility vehicular scenarios. This paper presents a BEV-Fusi…
A Two-Stage ISAC Framework for Low-Altitude Economy Based on 5G NR Signals
Haisu Wu, Hong Ren, Cunhua Pan +5
The evolution of next-generation wireless networks has spurred the vigorous development of the low-altitude economy (LAE). To support this emerging field while remaining compatible…
4D Imaging in ISAC Systems: A Framework Based on 5G NR Downlink Signals
Haoyang Weng, Haisu Wu, Hong Ren +2
Integrated sensing and communication (ISAC) has emerged as a key enabler for sixth-generation (6G) wireless networks, supporting spectrum sharing and hardware integration. Beyond c…
