Joint CFO-Channel Estimation under Strong Inter-Cell Interference for Low-Altitude Radio Mapping
Bowen Li, Haotian Zhang, Mu Jia +2
Extending terrestrial networks into low-altitude airspace is a practical way to support aerial services, and accurate low-altitude radio maps are essential for characterizing terre…
Privacy-Preserving Federated Radio Map Learning for Wireless Digital Twins via Adaptive Noise Allocation
Jijia Tian, Hao Wang, Mu Jia +3
Radio maps provide a foundational data layer for wireless digital twins, and federated learning offers a natural framework for their distributed construction without centralizing r…
Physics-Aware Tensor Reconstruction for Radio Maps in Pixel-Based Fluid Antenna Systems
Mu Jia, Hao Sun, Junting Chen +1
The deployment of pixel-based antennas and fluid antenna systems (FAS) is hindered by prohibitive channel state information (CSI) acquisition overhead. While radio maps enable proa…
