Outage probability of selective decode and forward relaying with secrecy constraints

open access: yesCoRR, 2011
We study the outage probability of opportunistic relay selection in decode-and-forward relaying with secrecy constraints. We derive the closed-form expression for the outage probability. Based on the analytical result, the asymptotic performance is then investigated. The accuracy of our performance analysis is verified by the simulation results.

On the Optimum Secrecy Outage Probability and Ergodic Secrecy Rate over Wireless Channels

open access: yes
We study the secrecy of wireless channels in the presence of an eavesdropper, where the channels are random and the transmitter only has knowledge of the channel statistics. We investigate the optimal input distribution with respect to several secrecy metrics: the Secrecy Outage Probability (SOP), defined as the probability that the coding rate $r ...

A Simple Evaluation for the Secrecy Outage Probability over Generalized-K Fading Channels

open access: yes, 2019
A simple approximation for the secrecy outage probability (SOP) over generalized- K fading channels is developed. This approximation becomes tighter as the average signal-to-noise ratio (SNR) of the wiretap channel decreases.
