Secure transmission in amplify-and-forward diamond networks with a single eavesdropper
Secure transmission in amplify-and-forward diamond networks with a single eavesdropper
Unicast communication over a network of M parallel relays in the presence of an eavesdropper is considered. The relay nodes, operating under individual power constraints, amplify and forward the signals received at their inputs. In this scenario, the problem of the maximum secrecy rate achievable with AF relaying is addressed. …
