Joint Receive Antenna Selection and Beamforming in RIS-Aided MIMO Systems
Chongjun Ouyang, Ali Bereyhi, Saba Asaad +2
This work studies a low-complexity design for reconfigurable intelligent surface (RIS)-aided multiuser multiple-input multiple-output systems. The base station (BS) applies receive…
Statistical-CSI-Based Antenna Selection and Precoding in Uplink MIMO
Chongjun Ouyang, Ali Bereyhi, Saba Asaad +2
Classical antenna selection schemes require instantaneous channel state information (CSI). This leads to high signaling overhead in the system. This work proposes a novel joint rec…
MIMO-ISAC: Performance Analysis and Rate Region Characterization
Chongjun Ouyang, Yuanwei Liu, Hongwen Yang
This article analyzes the performance of sensing and communications (S\&C) achieved by a multiple-input multiple-output downlink integrated S\&C (ISAC) system. Three ISAC scenarios…
Integrated Sensing and Communications: A Mutual Information-Based Framework
Chongjun Ouyang, Yuanwei Liu, Hongwen Yang +1
Integrated sensing and communications (ISAC) is potentially capable of circumventing the limitations of existing frequency-division sensing and communications (FDSAC) techniques. H…
Capacity Scaling Law in Massive MIMO with Antenna Selection
Chongjun Ouyang, Hao Xu, Xujie Zang +1
Antenna selection is capable of handling the cost and complexity issues in massive multiple-input multiple-output (MIMO) channels. The sum-rate capacity of a multiuser massive MIMO…
Lens Antenna Arrays-Assisted mmWave MU-MIMO Uplink Transmission: Joint Beam Selection and Phase-Only Beamforming Design
Chongjun Ouyang, Hao Xu, Xujie Zang +1
This paper considers a lens antenna array-assisted millimeter wave (mmWave) multiuser multiple-input multiple-output (MU-MIMO) system. The base station's beam selection matrix and…
