Hybrid Precoding Revisited: Low-Dimensional Subspace Perspective for MU-MIMO Systems
Mintaek Oh, Jinseok Choi
This letter presents a low-complexity hybrid precoding framework for multiuser multiple-input multiple-output (MIMO) systems by leveraging a low-dimensional subspace property. Unde…
Efficient RF Chain Selection for MIMO Integrated Sensing and Communications: A Greedy Approach
Subin Shin, Seongkyu Jung, Jinseok Choi +1
In multiple-input multiple-output integrated sensing and communication (MIMO ISAC) systems, radio frequency chain (i.e., RF chain) selection plays a vital role in reducing hardware…
Space-Time Beamforming for LEO Satellite Communications
Jungbin Yim, Jinseok Choi, Jeonghun Park +2
Inter-beam interference poses a significant challenge in low Earth orbit (LEO) satellite communications due to dense satellite constellations. To address this issue, we introduce s…
Scalable Beamforming Design for Multi-RIS-Aided MU-MIMO Systems with Imperfect CSIT
Mintaek Oh, Jinseok Choi
This paper presents a scalable beamforming design for maximizing the spectral efficiency (SE) of multi-reconfigurable intelligent surface (RIS)-aided communications through joint o…
