This paper studies the secrecy rate maximization problem of a secure wireless
communication system in the presence of multiple eavesdroppers. The security of the …

Secrecy transmission is investigated for a cooperative jamming scheme, where a multi-
antenna jammer generates artificial noise (AN) to confuse eavesdroppers. Two kinds of …

In this paper, we study different secrecy rate optimization techniques for a multiple-input–
multiple-output (MIMO) secrecy channel, where a multiantenna cooperative jammer is …

This paper investigates cooperative security in wireless networks, where a source (Alice)
intends to transmit a confidential message to a legitimate destination (Bob), with the help of …

The issue of physical layer security for single-input-multiple-output (SIMO) wiretap channel
with uncoordinated cooperative jamming (UCJ) is addressed in this letter, and we focus on …

A practical uncoordinated cooperative jamming (UCJ) scheme is proposed in this paper to
enhance the physical layer security of the single-input-single-output (SISO) wiretap channel …

Cooperative jamming is an approach that has been recently proposed for improving
physical layer based security for wireless networks in the presence of an eavesdropper …

This paper investigates the secrecy rate maximization problem for the multiple-input-single-
output multiple-antenna-eavesdropper (MISOME) wiretap channel with multiple randomly …

In this paper, we consider physical layer security in wireless communication networks in
which a source (Alice) intends to send a confidential message to a legitimate destination …

This paper proposes a new location-based multicasting technique, for dual phase amplify-
and-forward (AF) large networks, aiming to improve the security in the presence of non …
