In massive MIMO wiretap settings, the base station can significantly suppress
eavesdroppers by narrow beamforming toward legitimate terminals. Numerical …

The achievable secrecy rates for a cell-free massive multiple-input multiple-output (MIMO) in
the presence of a single-antenna active eavesdropper are derived and compared with that …

In this paper, we study the impacts of transmit antenna selection on the secrecy performance
of massive MIMO systems. We consider a wiretap setting in which a fixed number of transmit …

This paper studies the impact of transmit antenna selection on the secrecy performance of
massive MIMO wiretap channels. We consider a scenario in which a multi-antenna …

In recent years, physical layer security has been regarded as a promising concept to provide
secure communications in next generation mobile systems, where theoretically massive …

Passively overheard massive multiple-input multiple-output (MIMO) settings are capable of
suppressing eavesdroppers via narrow beamforming towards legitimate receivers. This …

Massive MIMO has the potential to thwart passive eavesdropping as the signals transmitted
by a large antenna array become highly focused. Indeed, the impact of passive …

In this study, we consider the physical layer security in the downlink of a Massive MIMO
system employing one-bit quantization at the base station (BS). We assume an active …

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 …
