In this paper, we consider max-min fairness for a downlink two-user multi-input single-output
(MISO) system with imperfect channel state information available at transmitter (CSIT) taking …

This paper studies the beamforming design problem of a multiuser downlink network,
assuming imperfect channel state information known to the base station. In this scenario, the …

This paper studies robust transmission schemes for multiple-input single-output (MISO)
wiretap channels. Both the cases of direct transmission and cooperative jamming with a …

This paper investigates secrecy rate optimization problems for a multiple-input-single-output
(MISO) secrecy channel in the presence of multiple multiantenna eavesdroppers …

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 …

Robust quality-of-service (QoS)-based and secrecy rate-based secure transmission designs
are investigated for a multiple-input single-output system with multiple eavesdroppers and a …

In this paper, we consider a cellular downlink multiple-input-single-output (MISO)
nonorthogonal multiple access (NOMA) secure transmission system, where users are …

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 letter investigates the secure transmission optimization in a multibeam satellite
downlink network with multiple eavesdroppers, where each legitimate user is wiretapped by …

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 …
