Communication secrecy in the wireless systems has unique challenges due to broadcasting
nature of the radio waves, as compared to its wire-line counterpart. At the same time …

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 …

Abstract Physical Layer Security (PLS) is an emerging paradigm employed to enhance
wireless network security without relying on higher-layer encryption techniques. PLS …

In this work, by considering a variety of realistic hardware impairments, we aim to enhance
the security of a cooperative relaying network, where a source intends to transmit its …

In this paper, we investigate a multiuser massive MIMO amplify-and-forward relay uplink,
where low-resolution analog-to-digital convertors (ADCs) are used at the relay station (RS) …

By taking a variety of realistic hardware imperfections into consideration, we propose an
optimal power allocation (OPA) strategy to maximize the instantaneous secrecy rate of a …

In this paper, considering the practical channel impairments known as pilot contamination
and channel aging induced by both Doppler shift and phase noise, we analyze the uplink …

Physical layer security (PLS) is becoming an interesting subject since it guarantees to
deliver the most consistent and secure communication in wireless systems in both present …

Investigating the physical layer security performance of full-duplex (FD) radio transceivers
has been the subject of numerous research studies. However, self-interference cancellation …

Channel impairments are major limiting factors in the performance of large-scale antenna
systems. In this paper, we analyze the impacts of practical channel impairments caused by …
