Joint Receive Antenna Selection and Beamforming in RIS-Aided MIMO Systems

no code implementations28 Dec 2022 Chongjun Ouyang, Ali Bereyhi, Saba Asaad, Ralf R. Müller, Hongwen Yang

This work studies a low-complexity design for reconfigurable intelligent surface (RIS)-aided multiuser multiple-input multiple-output systems.

Statistical-CSI-Based Antenna Selection and Precoding in Uplink MIMO

no code implementations28 Dec 2022 Chongjun Ouyang, Ali Bereyhi, Saba Asaad, Ralf R. Müller, Hongwen Yang

This work proposes a novel joint receive antenna selection and precoding scheme for multiuser multiple-input multiple-output uplink transmission that relies only on the long-term statistics of the CSI.

Matching Pursuit Based Scheduling for Over-the-Air Federated Learning

no code implementations14 Jun 2022 Ali Bereyhi, Adela Vagollari, Saba Asaad, Ralf R. Müller, Wolfgang Gerstacker, H. Vincent Poor

Compared to the state-of-the-art, the proposed scheme poses a drastically lower computational load on the system: For $K$ devices and $N$ antennas at the parameter server, the benchmark complexity scales with $\left(N^2+K\right)^3 + N^6$ while the complexity of the proposed scheme scales with $K^p N^q$ for some $0 < p, q \leq 2$.
