Cooperative Jamming with AF Relay in Power Monitoring and Communication Systems for Mining

In underground mines, physical layer security (PLS) technology is a promising method for the effective and secure communication to monitor mining process. Therefore, in this paper, we investigate PLS of an amplify-and-forward relay-aided system power monitoring systems mining, with consideration multiple eavesdroppers. Explicitly, propose scheme cooperative jamming precoding full-duplex considering imperfect channel state information. To maximize secrecy rate communications, block coordinate descent algorithm used design matrix at both source relay. Furthermore, effectiveness convergence proposed high information uncertainty have been proven.
