The Internet of Things (IoT) will feature pervasive sensing and control capabilities via a
massive deployment of machine-type communication (MTC) devices. The limited hardware …

Providing secure communications over the physical layer with the objective of achieving
secrecy without requiring a secret key has been receiving growing attention within the past …

Multiple antennas have played an essential role in spatial multiplexing and diversity
transmission for a wide range of communication applications. Most advances in the design …

In this article, we investigate a secure uplink multiple-input multiple-output communication
system, in which the multiple users transmit information to a legitimate access point (AP) …

Deep neural networks is a popular technique that has been applied successfully to domains
such as image processing, sentiment analysis, speech recognition, and computational …

We consider secure downlink multiple-input–multiple-output (MIMO) communications
between a transmitter and multiple users when there exists a passive eavesdropper. A …

Multi-user interference (MUI) is usually considered to be a harmful component in wireless
communications. However, recently emerged symbol-level precoding techniques can …

This work examines the use of two-way training to efficiently discriminate the channel
estimation performances at a legitimate receiver (LR) and an unauthorized receiver (UR) in …

In this work, we investigate the security performance obtained by employing a practical
precoded orthogonal space time block coding method (POSTBC) in MISO wireless …

In this paper, we consider a 2× 2 space-time line coded (STLC) system having two-transmit
and two-receive antennas. To improve the secrecy rate of the STLC system, in which an …
