Abstract: A Cramér-Rao bound (CRB) optimization framework for near-field sensing (NISE) with continuous-aperture arrays (CAPAs) is proposed. In contrast to conventional spatially discrete arrays ...
Abstract: Phase-time arrays (PTAs), integrating phase shifters and true-time delays, emerge as a cost-effective and energy-efficient architecture for frequency-dependent beamforming in wideband ...
