Tight Wavelet Frames on Graphs via Isometric Group Embedding

This feed aggregates recent arXiv papers (communications, signal processing, ML for physical-layer systems, and graph methods). Notable contributions: a denoising-autoencoder-assisted physical-layer secret key generation (improves key agreement reliability and randomness); AUGUST, a conditional generative (diffusion + flow) approach for high-fidelity UAV point-cloud sensing and tracking from radar/array echoes; LIVE-RIS, a real-time UAV-mounted reconfigurable intelligent surface prototype with EKF-based pose prediction and in‑flight reconfiguration; SLIPT-enabled ground-to-UAV FSO with optical
