Outage Probability of Secrecy Capacity over Correlated Log-Normal Fading Channels

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 cert...

More Information
Summary: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.
