Achievable Rate of Near-Field Communications Based on Physically Consistent Models
Mohamed Akrout, Volodymyr Shyianov, Faouzi Bellili +2
This paper introduces a novel information-theoretic approach for studying the effects of mutual coupling (MC), between the transmit and receive antennas, on the overall performance…
Optimizing Binary Symptom Checkers via Approximate Message Passing
Mohamed Akrout, Faouzi Bellili, Amine Mezghani +1
Symptom checkers have been widely adopted as an intelligent e-healthcare application during the ongoing pandemic crisis. Their performance have been limited by the fine-grained qua…
Minimum Symbol Error Probability Low-Resolution Precoding for MU-MIMO Systems With PSK Modulation
Erico S. P. Lopes, Lukas T. N. Landau, Amine Mezghani
We propose an optimal low-resolution precoding technique that minimizes the symbol error probability of the users. Unlike existing approaches that rely on QPSK modulation, for the…
Modulating Intelligent Surfaces for Multi-User MIMO Systems: Beamforming and Modulation Design
Haseeb Ur Rehman, Faouzi Bellili, Amine Mezghani +1
This paper introduces a novel approach of utilizing the reconfigurable intelligent surface (RIS) for joint data modulation and signal beamforming in a multi-user downlink cellular…
On the Robustness of Deep Reinforcement Learning in IRS-Aided Wireless Communications Systems
Amal Feriani, Amine Mezghani, Ekram Hossain
We consider an Intelligent Reflecting Surface (IRS)-aided multiple-input single-output (MISO) system for downlink transmission. We compare the performance of Deep Reinforcement Lea…
Sparse Linear Precoders for Mitigating Nonlinearities in Massive MIMO
Amine Mezghani, Daniel Plabst, Lee A. Swindlehurst +2
Dealing with nonlinear effects of the radio-frequency(RF) chain is a key issue in the realization of very large-scale multi-antenna (MIMO) systems. Achieving the remarkable gains p…
Joint Active and Passive Beamforming Design for IRS-Assisted Multi-User MIMO Systems: A VAMP-Based Approach
Haseeb Ur Rehman, Faouzi Bellili, Amine Mezghani +1
This paper tackles the problem of joint active and passive beamforming optimization for an intelligent reflective surface (IRS)-assisted multi-user downlink multiple-input multiple…
