Subcarrier‐pair based joint resource allocation for secure cooperative OFDM system with multiple untrusted AF relays
Abstract In this paper, a cooperative orthogonal frequency division multiplexing system with multiple untrusted amplify‐and‐forward relays is considered. Since there exists no direct link between source and user because of the shadowing effect, a positive system secrecy rate cannot be obtained. Addr...
