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…
Approximate Message Passing for Indoor THz Channel Estimation
Viktoria Schram, Ali Bereyhi, Jan-Nico Zaech +2
Compressed sensing (CS) deals with the problem of reconstructing a sparse vector from an under-determined set of observations. Approximate message passing (AMP) is a technique used…
