In this paper, we investigate the artificial noise-aided jamming design for a transmitter
equipped with large antenna array in Rician fading channels. We figure out that when the …

In this work, we study how fast we are able to scale down the power for both training and
data transmission while guaranteeing security in a massive MIMO network without the help …

In recent years, massive multiple-input multiple-output (MIMO) has been regarded as a
promising technique in the fifth-generation (5G) communication systems. With the ability of …

This letter investigates the secure transmission in a multi-user massive MIMO system over
Ricean fading channel in the presence of a multi-antenna eavesdropper. In order to reduce …

In this paper, we investigate secure and reliable transmission strategies for multi-cell multi-
user massive multipleinput multiple-output (MIMO) systems in the presence of an active …

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

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 …

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 design of secure communication for time-division duplex multi-
cell multi-user massive multiple-input-multiple-output (MIMO) systems with active …
