A Single-RF Architecture for Multiuser Massive MIMO via Reflecting Surfaces
Ali Bereyhi, Vahid Jamali, Ralf R. Müller +3
In this work, we propose a new single-RF MIMO architecture which enjoys high scalability and energy-efficiency. The transmitter in this proposal consists of a single RF illuminator…
Robustness of Low-Complexity Massive MIMO Architectures Against Passive Eavesdropping
Ali Bereyhi, Saba Asaad, Ralf R. Müller +3
Invoking large transmit antenna arrays, massive MIMO wiretap settings are capable of suppressing passive eavesdroppers via narrow beamforming towards legitimate terminals. This imp…
PAPR-Limited Precoding in Massive MIMO Systems with Reflect- and Transmit-Array Antennas
Ali Bereyhi, Vahid Jamali, Ralf R. Müller +3
Conventional hybrid analog-digital architectures for millimeter-wave massive multiple-input multiple-output (MIMO) systems suffer from poor scalability and high implementational co…
Intelligent Surface-Aided Transmitter Architectures for Millimeter Wave Ultra Massive MIMO Systems
Vahid Jamali, Antonia M. Tulino, Georg Fischer +2
In this paper, we study two novel massive multiple-input multiple-output (MIMO) transmitter architectures for millimeter wave (mmWave) communications which comprise few active ante…
Scalable and Energy-Efficient Millimeter Massive MIMO Architectures: Reflect-Array and Transmit-Array Antennas
Vahid Jamali, Antonia M. Tulino, Georg Fischer +2
Hybrid analog-digital architectures are considered as promising candidates for implementing millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) systems since the…
GLSE Precoders for Massive MIMO Systems: Analysis and Applications
Ali Bereyhi, Mohammad Ali Sedaghat, Ralf R. Müller +1
This paper proposes the class of Generalized Least-Square-Error (GLSE) precoders for multiuser massive MIMO systems. For a generic transmit constellation, GLSE precoders minimize t…
