We propose a low complexity transmit signal design scheme for achieving information-
theoretic secrecy over a MIMO wiretap channel driven by finite-alphabet inputs. We assume …

We propose two beamforming schemes supporting multi-stream transmission in multi-input
multi-output multi-antenna eavesdropper wiretap channels with imperfect channel state …

We consider transmission of confidential data over multiple-input single-output multiple-
eavesdropper (MISOME) Rayleigh-fading wiretap channels. The transmitter has access to …

In this paper, we examine the secrecy performance of two-way relaying between a large-
scale multiple antenna base station (BS) and a single antenna mobile user (MU) in the …

Interference is usually regarded as a detrimental factor that degrades the performance of a
wireless network. However, when it is used properly, the security of transmission can be …

In this paper, to realize a power-efficient, user-centric and physical layer security-addressing
system, we investigate total power minimization by jointly designing antenna selection and …

We present a secure multi-user multi-antenna transmission framework based on artificial-
noise-aided linear zero-forcing beamforming, with limited channel state information …

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 …

The advances of multi-antenna techniques has recently led to renewed interest in physical-
layer secrecy, a meaningful topic that enables us to prevent eavesdroppers from retrieving …

We study secure multi-antenna transmission with limited feedback from the intended
receiver and no feedback from the malicious eavesdropper. Our system uses the artificial …
