Sensing-Based Two-Stage Transmission Framework for Near-Field mmWave Covert Communications

This letter investigates a two-stage near-field covert communication for wideband millimeter-wave (mmWave) systems. During the sensing stage, we propose a novel sensing scheme exploiting controllable near-field beam squint, enabled by phase shifters (PSs) and true-time delays (TTDs), to acquire the channel state inform...
