Outage Secrecy Capacity Over Correlated Fading Channels at High SNR

Xian Liu

The information-theoretic secrecy of correlated log-normal fading channels is investigated. A closed-form expression is derived for the asymptotic outage probability of secrecy capacity in the high SNR regime. It is revealed that the increased correlation may reduce the outage probability under certain condition.

In this paper, we analyze the secrecy performance assuming correlated generalized gamma fading for the legitimate and eavesdropper channels. Specifically, we derive expressions for the probability of non-zero secrecy capacity, a lower bound on the secrecy outage probability and the average secrecy capacity in case of high signal-to-noise ratio (SNR). Monte Carlo simulations were then run verifying the accuracy of our analysis.

In this paper, the information-theoretic secrecy of the Hoyt fading channel is investigated. The analytical formulae of the outage probability of secrecy capacity in the regime of high SNR and the probability of strictly positive secrecy capacity are derived. Both are in terms of the hypergeometric function of two variables (i.e., Appell's function). Profile examples are illustrated.
