Blind Radio Mapping via Spatially Regularized Bayesian Trajectory Inference
Zheng Xing, Junting Chen
Radio maps enable intelligent wireless applications by capturing the spatial distribution of channel characteristics. However, conventional construction methods demand extensive lo…
Correlated-Sequence Differential Privacy
Yifan Luo, Meng Zhang, Jin Xu +2
Data streams collected from multiple sources are rarely independent. Values evolve over time and influence one another across sequences. These correlations improve prediction in he…
Unsupervised Radio Map Construction in Mixed LoS/NLoS Indoor Environments
Zheng Xing, Junting Chen
Radio maps are essential for enhancing wireless communications and localization. However, existing methods for constructing radio maps typically require costly calibration processe…
Blind Construction of Angular Power Maps in Massive MIMO Networks
Zheng Xing, Junting Chen
Channel state information (CSI) acquisition is a challenging problem in massive multiple-input multiple-output (MIMO) networks. Radio maps provide a promising solution for radio re…
