This letter studies the practical design of secure transmissions without knowing the
eavesdropper's channel state information (ECSI). An ECSI-irrelevant metric is introduced to …

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 …

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 …

This letter studies information-theoretic security without knowing the eavesdropper's channel
fading state. We present an alternative secrecy outage formulation to measure the …

Physical layer security has recently been regarded as an emerging technique to
complement and improve the communication security in future wireless networks. The …

We evaluate the effective secrecy throughput of the multiple-input multiple-output multiple-
antenna eavesdropper (MIMOME) wiretap channel with antenna selection at the legitimate …

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 …

We design a novel artificial-noise-aided secure ON-OFF transmission scheme in a wiretap
channel. We consider a practical scenario, where the multi-antenna transmitter only obtains …

Secure communication with noisy feedback is studied in this correspondence. Unlike the
majority of previous research efforts where the eavesdropper's channel state information …

The paper proposes a novel artificial noise (AN) injection strategy in multiple-input single-
output multiple-antenna-eavesdropper (MISOME) systems under imperfect channel …
