In this paper, we investigate the impact of phase noise on the secrecy performance of
downlink massive MIMO systems in the presence of a passive multiple-antenna …

To keep the hardware costs of future communications systems manageable, the use of low-
cost hardware components is desirable. This is particularly true for the emerging massive …

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 …

Secure downlink transmission in massive multiple-input multiple-output (MIMO) systems has
sparked great research enthusiasm. However, the secrecy of uplink transmission is equally …

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 …

In this paper, we consider physical layer security provisioning in multicell massive multiple-
input-multiple-output (MIMO) systems. Specifically, we consider secure downlink …

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

In this paper, we investigate the secure downlink transmission in a multi-user massive
multiple-input multiple-output system assuming there is a passive multi-antenna …

An overview over secure communication in massive multiple-input multiple-output (MIMO)
systems is presented. A massive MIMO base-station serves multiple user nodes by …
