POPT: Physics-Informed Deep Learning for Phase-Only Positioning in Distributed MIMO

This article develops a physics-informed deep learning framework for single-snapshot 3D phase-only positioning in narrowband phase-coherent distributed multiple-input multiple-output (D-MIMO) networks under two-ray propagation. Unlike prior phase-coherent D-MIMO localization methods that largely assume line-of-sight (L...

Synthetic Aperture Based Moving Targets Localization Using Mobile OTFS Radar

This paper proposes a low-complexity localization framework for moving targets using a single-antenna mobile radar platform with orthogonal time-frequency space (OTFS) waveforms. Unlike conventional approaches requiring antenna arrays or multistatic configurations, the proposed method exploits synthetic aperture (SA) m...
