Massive MIMO attains high spectral and power efficiency transmission by leveraging a large
number of transmit antennas. However, to capture the benefits of massive MIMO, each …

We investigate the optimality and power allocation algorithm of beam domain transmission
for single-cell massive multiple-input multiple-output (MIMO) systems with a multi-antenna …

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

In this work, we present a scheme of physical layer secret key generation for Millimeter wave

Physical-layer secure transmissions require that the legitimate parties Alice and Bob have
certain signal advantages over the eavesdropper Eve. Unfortunately, it is still unknown what …

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 …

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

In this paper, a multiple-input multiple-output wiretap channel model is studied, where the
information packet sent from the transmitter to the desired receiver is wiretapped by a …

This paper investigates the integration of a reconfigurable intelligent surface (RIS) into a
secure multiuser massive multiple-input multiple-output (MIMO) system in the presence of …
