This article focuses on a two-hop relay system, where a potential malicious single-antenna
relay may forward altered symbols to a base station (BS) equipped with massive antennas …

Physical layer security is a promising research direction for the fifth-generation and beyond
networks. This paper investigates the physical layer security of massive multiple-input …

In the time-division-duplex (TDD) system, the channel state information (CSI) is mainly
obtained through channel estimation. The active eavesdropper is able to attack the channel …

Previous works on multi-way massive MIMO relay only consider either Matched Filter
(MF)/Maximum Ratio Transmission (MRT) or Zero Forcing as the pairs for the detector (or …

We consider a single-cell massive multiple-input multiple-output (MIMO) system in which a
base station (BS) with a large number of antennas simultaneously transmits to K single …

This paper considers a decode-and-forward (DF) multi-way massive multiple-input multiple-
output (MIMO) relay system where many users exchange their data with the aid of a relay …

This paper investigates the secure transmission in multi-pair massive multiple-input multiple-
output amplify-and-forward (AF) relaying networks under active pilot spoofing attacks. The …

In massive millimeter-wave (mmWave) multiple-input–multiple-output (MIMO) systems,
eavesdroppers may transmit the identical pilot sequences as legitimate users to manipulate …

In this paper, we consider multiple-pair communication in massive MIMO relay network,
wherein K single antenna source nodes deliver their messages to the corresponding K …

In this study, we consider a multiway massive multi‐input multi‐output (MIMO) relay network
over Rician fading channels, where all users intend to share their information with the other …
