Security in generalized gamma fading channels with dual-branch selection diversity receiver

In this paper, a single input single output (SISO) scheme is proposed to analyze the security in Generalized Gamma (GG) fading channels with dual-branch selection diversity receiver in the presence of numerous eavesdroppers. The primary objective of this paper is to analyze the effects of shaping parameters ω and β with S number of eavesdroppers on the secrecy performance of the proposed scheme. The closed-form analytical expressions of the probability of non-zero secrecy capacity (PNZSC) and the secure outage probability (SOP) have been derived and verified with the simulation one. Our results revealed that the secrecy performance degrades with increasing in the shaping parameters related to eavesdroppers as well as increasing in the number of eavesdroppers whereas upgrades with increasing in the shaping parameter of the main channel.
