Secrecy Outage Probability Analysis over Malaga-Malaga Fading Channels

2018 IEEE International Conference on Communications (ICC), 2018
As a novel statistical model, Malaga distribution is proposed recently, which covers many commonly used fading models as special cases. The secure transmission of information over the Malaga fading channels has not been discussed in literature.

Secrecy outage probability and jamming coverage of UAV-enabled friendly jammer

2017 11th International Conference on Signal Processing and Communication Systems (ICSPCS), 2017
In this paper, we examine the secrecy performance of an unmanned aerial vehicle (UAV) equipped with an air-to-ground jammer and a ground communications network comprising a legitimate transmitter-receiver pair and an eavesdropper. We consider two scenarios: stationary UAV jammer and mobile UAV jammer. In the first scenario, we derive the secrecy outage

Secrecy Outage Probability of MIMO Diversity Schemes Over Integer and Real-Valued Nakagami Fading Channels

IEEE Wireless Communications Letters, 2022
This letter studies the secrecy outage probability of diversity schemes (i.e., antenna-user selection with maximal ratio combining (AUS-MRC) scheme and the user selection with space-time block coding (US-STBC)) over arbitrary (i.e., integer and real ...

Rethinking the Secrecy Outage Formulation: A Secure Transmission Design Perspective

IEEE Communications Letters, 2011
This letter studies information-theoretic security without knowing the eavesdropper's channel fading state. We present an alternative secrecy outage formulation to measure the probability that message transmissions fail to achieve perfect secrecy.

Improving Secrecy Outage Probability with Symbol Extension

2014 IEEE 79th Vehicular Technology Conference (VTC Spring), 2014
This paper reveals symbol extension is capable of improving secrecy performance in the multiple-input single-output (MISO) wiretap channel. We propose a symbol extension scheme jointly with the existing beamforming and artificial noise generation strategy to exploit the time variation of fading channel.

Minimization of Secrecy Outage Probability With Artificial-Noise-Aided Beamforming for MISO Wiretap Channels

IEEE Communications Letters, 2020
The problem of optimal power allocation between the information-bearing signal and the artificial noise (AN) signal is addressed in this letter to enhance the physical layer security of the multiple-input-single-output wiretap channel. Differing from the
