Secrecy Outage Probability in Backscatter Communication Systems With Tag Selection

IEEE Wireless Communications Letters, 2021
In this letter, we propose a tag selection scheme to enhance the security transmission in a passive backscatter communication system with multiple tags and one eavesdropper, and analyze the secrecy outage probability (SOP). In particular, considering a practical non-linear energy harvesting model, we first determine the optimal dynamic reflection ...

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.

Secrecy outage probability of wirelessly powered wiretap channels

2016 24th European Signal Processing Conference (EUSIPCO), 2016
This paper considers a wirelessly powered wiretap channel, where an energy constrained information source, powered by a dedicated power beacon, communicates with a legitimate user in the presence of a passive eavesdropper. The source is assumed to have multiple antennas, while the other three nodes are equipped with a single antenna each. Considering a

Secrecy Outage Probability in Multi-RAT Heterogeneous Networks

IEEE Communications Letters, 2016
Practical difficulty in examining all base stations (BSs) to choose the best one providing secure transmission in heterogeneous networks (HetNets), we impose a BS association constraint in this letter that the BSs providing an average received signal power at the legitimate user greater than a predetermined receiving threshold can be candidate serving ...

On the ergodic secrecy capacity and secrecy outage probability of the MIMOME Rayleigh wiretap channel

Transactions on Emerging Telecommunications Technologies, 2015
AbstractIn this paper, we study the multiple‐input multiple‐output multiple‐eavesdropper wiretap channel in the nonergodic and ergodic scenarios, both with stationary Rayleigh distributed fading channels. For the ergodic scenario, we derive a new closed‐form expression for the ergodic secrecy capacity with full channel state information at the ...
