Heuristic inspired precoding for millimeter-wave MIMO systems with lens antenna subarrays
(Institute of Electrical and Electronics Engineers Inc., 2022)
A traditional array (TA) multiple-input multiple-output (MIMO) architecture in mmWave with hybrid beamforming suffers from high power consumption and hardware overhead. Therefore, a lens antenna subarray (LAS)-MIMO ...
Energy and spectral-efficient lens antenna subarray design in MmWave MIMO Systems
(IEEE-Institute Electrical Electronics Engineers Inc, 2022)
Lens antenna subarray (LAS) is one of the recently introduced technologies for future wireless networks that significantly improves the energy efficiency of multiple-input multiple-output (MIMO) systems while achieving ...
Physical layer authentication scheme in beamspace MIMO systems
(Institute of Electrical and Electronics Engineers Inc., 2022)
The broadcast nature of wireless communication makes it vulnerable to various security threats such as spoofing attacks. Physical layer (PL) authentication has emerged as a promising and powerful approach to secure future ...
Beam squint inspired multiple access technique in massive MIMO systems
(Institute of Electrical and Electronics Engineers Inc., 2022)
Massive multiple-input multiple-output (mMIMO) systems implementing wideband signaling have been found to suffer from beam squinting problem. In multicarrier systems, beam squint causes spreading of the beam to multiple ...
