Fig. 3From: Secrecy outage of threshold-based cooperative relay network with and without direct linksComparison of outage probability under three scenarios: (1) with direct link between both S−D and S−E, (2) with direct link only between S and E, and (3) with no direct link between both S−D and S−E for 1/α=6 and 9 dB, R s =1.0, and γth=3 dB of single balanced relay systemBack to article page
