Unified Analysis of Secrecy Capacity Over N* Nakagami Cascaded Fading Channel

With fast growth of wireless services, there is a need to investigate the performance of a confidential communication through the wireless fading channel. In this work, a study is conducted on the secrecy outage performance of wireless system operating over N
^*
Nakagami cascaded fading channel. First, the secrecy outage probability (SOP) and the probability of strictly positive secrecy capacity (SPSC)are derived in closed-form using Meijer-G function with single eavesdropper. To extend the discussion to multi eavesdroppers’ scenario, the case of two eavesdroppers areconsidered. In particular, SOP and SPSC are derived in closed-form expressions using the extended generalized bivariate Miejer-G function (EGBMGF).
