This paper studies different secrecy rate optimization problems for a multiple-input–multiple-
output (MIMO) secrecy channel. In particular, we consider a scenario where a …

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 letter investigates robust secrecy rate optimization techniques for a multiple-input-
multiple-output (MIMO) wiretap channel in the presence of a multiantenna eavesdropper. In …

Consider a multi-input multi-output (MIMO) channel wiretapped by multiple multi-antenna
eavesdroppers. Assuming imperfect eavesdroppers' channel state information (CSI) at the …

In recent years there has been growing interest in study of multi-antenna transmit designs for
providing secure communication over the physical layer. This paper considers the scenario …

Recently, there has been growing interest in secure communication via multi-antenna
physical-layer designs. In this paper, we consider a transmit covariance design for a secrecy …

Consider a scenario in which an MISO channel is overheard by multiple single-antenna
eavesdroppers. The transmitter has perfect channel state information (CSI) with the …

This paper studies the robust beamforming design problem for a multiple-input single-output
(MISO) secrecy channel with a single-antenna eavesdropper. Due to the illegal nature, the …

In this paper, the secure transmission strategy for a multi-input-single-output multi-
eavesdropper system with coexistence of a secure user (Bob) and a normal user (NU) is …
