Annotation-Free Indoor Radio Mapping via Physics-Informed Trajectory Inference

This collection contains multiple papers with clear implications for wireless privacy, coding leakage, and hardware-accelerated communications. Two papers (CSI-based PADP and RSS HMM methods) demonstrate label-free indoor radio-map construction and trajectory recovery from Channel State Information or unlabeled RSS, enabling accurate indoor localization without IMUs or manual surveys — a privacy risk for covert tracking and mapping. RankGuard-Polar provides an algebraic/algorithmic framework to identify and certify information leakage when publishing subsets of polar-codeword coordinates, i.e.
