Toward Intelligent Skies: Signal Processing and AI Foundations of Low-Altitude Wireless Networks
Weijie Yuan, Geng Sun, Jiacheng Wang +7
The rapid growth of low-altitude aerial services and applications, driven by uncrewed aerial vehicles (UAVs), calls for a new class of digital infrastructure beyond conventional te…
Deflection-Optimal Spectral Design for Diagonal Screening in Sparse Phase Retrieval Initialization
Mengchu Xu, Yonina C. Eldar
Spectral initialization is a critical yet challenging step in sparse phase retrieval. Existing spectral design theory is largely tailored to dense phase retrieval, where the object…
Lattice Modulo Sampling
Yhonatan Kvich, Yonina C. Eldar
We propose a lattice-theoretic framework for modulo sampling of multidimensional bandlimited signals. Standard modulo analog-to-digital converters (ADCs) fold the signal component-…
Knowledge Distillation for Sensing-Assisted Long-Term Beam Tracking in mmWave Communications
Mengyuan Ma, Nhan Thanh Nguyen, Nir Shlezinger +3
Infrastructure-mounted sensors can capture rich environmental information to enhance communications and facilitate beamforming in millimeter-wave systems. This work presents an eff…
Holographic Surface Enabled Integrated Sensing and Communications
Haobo Zhang, Shuhao Zeng, Xinyuan Hu +12
Integrated sensing and communications (ISAC) is an essential 6G capability for joint data transmission and environmental sensing. To support 6G scenarios with stringent ISAC perfor…
Semi-Supervised Model-Free Bayesian State Estimation from Compressed Measurements
Anubhab Ghosh, Yonina C. Eldar, Saikat Chatterjee
We consider data-driven Bayesian state estimation from compressed measurements (BSCM) of a model-free process. The dimension of the temporal measurement vector is lower than that o…
