Near-Optimal Modulo-and-Forward Scheme for the Untrusted Relay Channel.
IEEE Transactions on Information Theory(2016)
摘要
This paper studies an untrusted relay channel, in which the destination sends artificial noise simultaneously with the source sending a message to the relay, in order to protect the source's confidential message. The traditional amplify-and-forward (AF) scheme shows poor performance in this situation because of the interference power dilemma. Providing better security by using stronger artificial ...
