The artificial noise (AN) scheme is an efficient strategy for enhancing the secrecy rate of a
multiple-input-single-output channel in the presence of a passive eavesdropper, whose …

In this paper, the secrecy outage performance of a multiple-input single-output (MISO)
wiretap channel is investigated. Different from previous works, we assume that the legitimate …

In this paper, we investigate a multiuser MIMO downlink with imperfect channel state
information (CSI) from the physical-layer security provision. In a classical transmitter (Alice) …

Secrecy on the physical layer is a promising technique to simplify the overall cross-layer
secrecy concept. In many recent works on the multiple antenna wiretap channel, perfect …

In this letter, we consider physical layer security in multiple-input single-output (MISO) fading
wiretap channels, where the transmitter utilizes a jamming-aided precoding transmission …

This paper examines linear beamforming methods for secure communications in a multiuser
wiretap channel with a single transmitter, multiple legitimate receivers, and a single …

This paper exploits co-channel interference (CCI) to secure the multi-antenna wiretap IFC
consisting of two source-destination-eavesdropper triples, where each source-destination …

The impact of antenna correlation on secrecy performance in wireless communication
networks is analyzed. This network consists of a signal antenna at the source, while receiver …

In this paper, the security issue in a multi-input-single-output (MISO) system in the presence
of multiple randomly distributed eavesdroppers (Eves) is investigated. The Eves are …

In this paper, the secrecy performance of transmit antenna selection/maximal ratio
combining systems in the absence and presence of co-channel interference (CCI) over η-μ …
