Decode-and-forward vs. amplify-and-forward scheme in physical layer security for wireless relay beamforming networks

This trend has attracted increasing concerns from both academia and industry. This paper addresses how physical layer security can protect secret data compare with the traditional cryptographic encryption and which is the better cooperative relaying scheme with the state of the art approached methods in wireless relaying beamforming network.
