What happened
This collection of recent wireless and signal-processing papers includes multiple advances (true-time-delay beamforming via the Radon transform, complex AMP with non-separable denoisers, fronthaul-efficient cell-free XL‑MIMO reception, HyperCEUNet channel estimation, multimodal V2X beam alignment, PRIMEX-based distributed fusion, Kalman/IKWAF adaptations, and pedagogical pulse‑shaping for superconducting qubits). Of particular security relevance is “Threat Detection and Resilience Techniques in PRS‑Assisted OTDOA 5G Positioning Systems,” which demonstrates that open physical‑layer PRS are amen
