Imperfect Resolution of Near-Field Beamfocusing for NOMA-Aided Physical Layer Security

B Zhuo, J Gu, G Zhang, H Yang - IEEE Internet of Things …, 2025 - ieeexplore.ieee.org
Since adopting the spherical wave model in near-field, the imperfect resolution of
beamfocusing has significantly enabled non-orthogonal multiple access (NOMA) technique …
