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…
Secure Coding via Gaussian Random Fields
Ali Bereyhi, Bruno Loureiro, Florent Krzakala +2
Inverse probability problems whose generative models are given by strictly nonlinear Gaussian random fields show the all-or-nothing behavior: There exists a critical rate at which…
Bayesian Inference with Nonlinear Generative Models: Comments on Secure Learning
Ali Bereyhi, Bruno Loureiro, Florent Krzakala +2
Unlike the classical linear model, nonlinear generative models have been addressed sparsely in the literature of statistical learning. This work aims to bringing attention to these…
On the Ergodic Mutual Information of Keyhole MIMO Channels With Finite-Alphabet Inputs
Chongjun Ouyang, Ali Bereyhi, Saba Asaad +3
This letter studies the ergodic mutual information (EMI) of keyhole multiple-input multiple-output channels having finite-alphabet input signals. The EMI is first investigated for…
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…
Phase Shift Keying on the Hypersphere: Peak Power-Efficient MIMO Communications
Christoph Rachinger, Ralf R. Müller, Johannes B. Huber
Phase Shift Keying on the Hypersphere (PSKH), a generalization of conventional Phase Shift Keying (PSK) for Multiple-Input Multiple-Output (MIMO) systems, is introduced. In PSKH, c…
