We study secure transmission considering the practical scenario in which only outdated
knowledge of the legitimate receiver's channel and statistical knowledge of the …

We design new secure on-off transmission schemes in wiretap channels with outdated
channel state information (CSI). In our design, we consider not only the outdated CSI from …

We propose a new secure transmission scheme in the multi-input multi-output multi-
eavesdropper wiretap channel. In this channel, the N A-antenna transmitter adopts transmit …

We examine the secrecy performance of three artificial-noise-aided secure transmission
schemes, namely, the partially adaptive, fully adaptive, and ON-OFF schemes. To this end …

This paper studies physical-layer secure transmissions from a transmitter to a legitimate
receiver against an eavesdropper over slow fading channels, taking into account the impact …

The issue of physical layer security in single-antenna wiretap channels with slow fading is
addressed in this letter. With the assumption of perfect channel state information (CSI) about …

In this paper, we study the secure transmission in multiple access wiretap channels when
the instantaneous channel state information (CSI) of the wiretap channels is unknown by the …

We investigate the optimal physical-layer secure transmission with artificial noise in the
wiretap channel with N antennas at the transmitter, a single antenna at the receiver, and M …

This paper addresses the establishment of secure communication links between Alice and
Bob in the presence of an eavesdropper (Eve). The proposed scenario assumes: 1) …

We propose a new framework for determining the wiretap code rates of single-input-single-
output multiantenna eavesdropper wiretap channels when the capacity of the …
