Due to the malicious attacks in wireless networks, physical layer security has attracted
increasing concerns from both academia and industry. The research on physical layer …

Physical layer security is a promising approach that can benefit traditional encryption
methods. The idea of physical layer security is to take advantage of the propagation …

In this paper, we consider an underlay multiple-input-multiple-output (MIMO) cognitive radio
network (CRN) including a pair of primary nodes, a couple of secondary nodes, and an …

Due to the open nature of wireless communication systems, the data transmission over
these networks are vulnerable to malicious attack. To safeguard the transmitted data …

In this paper, a multiuser space-time line code (MU-STLC) scheme is newly designed that
concurrently delivers multiple STLC signals to multiple users, and a preprocessing matrix for …

High speed and low latency have become the development trend of mobile communication
network. Orthogonal frequency division multiplexing (OFDM) technology has become the …

Modified transmit antenna selection (M-TAS)/Alamouti space-time block coding (STBC)
schemes have been shown to achieve superior error performance together with a reduced …

The Internet of Things (IoT) facilitates physical things to detect, interact, and execute
activities on‐demand, enabling a variety of applications such as smart homes and smart …

针对主动窃听场景下单输入单输出(single-input single-output, SISO) 自适应调制频谱效率低和
物理层安全(physical layer security, PLS) 性能差的问题, 提出了一种多输入多输出(multiple …

In this paper we investigate the secure throughput of selective decode-and-forward relaying
where the legitimate transmitter has no knowledge of the instantaneous channel state …
