In this paper, the secrecy sum-rate performance of single cell downlink massive multiple-
input-multiple-output (MIMO) systems is investigated in the presence of an eavesdropper …

In massive multiple-input multiple-output (MIMO) systems, idle users may passively overhear
the signal transmitted to the intended user, known as internal eavesdroppers. In order to …

We analyze the ergodic secrecy rate of multi-cell downlink systems assuming that the
number of base station (BS) antennas per cell, the number of mobile users, and the number …

Spectral efficiency, energy efficiency, and security are cornerstones for the upcoming 5G
systems. In this study, the issue of how the energy and spectral efficiency of multiuser …

In this paper, we study linear precoding for a secure multi-cell massive multiple-input
multiple-output (MIMO) downlink system employing artificial noise generation. We consider …

This paper studies the secrecy performance of the cell-free massive multi-input multi-output
(MIMO) system, where access points (APs) are equipped with a mixed analog-to-digital …

Random unitary beamforming (RUB) can reduce the implementation complexity of massive
multiple-input singleoutput (MIMO) downlink transmission by only requiring partial channel …

This paper investigates the secrecy performance of the Cell-Free massive multiple-input
multiple-output network with finite resolution analog-to-digital converters at the access points …

In this paper, we investigate the effect of radiated power scaling (RPS) factors on the secrecy
performance of multiuser massive multiple-input multiple-output (MIMO) system. We …

In this paper we study the secrecy performance of a downlink massive multiple-input
multiple-output (MIMO) system in the presence of pilot spoofing attack (PSA). Specifically …
