Generative Spectrum Cartography: Unified Reconstruction and Active Sensing via Diffusion Models

arXiv:2512.20108v2 Announce Type: replace Abstract: High-fidelity spectrum cartography is important for spectrum monitoring and wireless situational awareness, especially in satellite-based wide-area sensing scenarios where measurements are sparse, noisy, and often low-bit quantized. In such settings, two coupled challenges arise: accurate reconstruction from severely incomplete measurements and efficient allocation of additional sensing resources under a limited sensing budget.
