Secrecy performance of dual-hop threshold relaying system with diversity reception
C. Kundu, T. M. N. Ngatched, O. A. Dobre
In this paper, the secrecy of a cooperative system consisting of a single source, relay, destination and eavesdropper is analyzed. The threshold-selection decode-and-forward relay…
Relay Selection to Improve Secrecy in Cooperative Threshold Decode-and-Forward Relaying
C. Kundu, T. M. N. Ngatched, O. A. Dobre
In this paper, relay selection is considered to enhance security of a cooperative system with multiple threshold-selection decode-and-forward (DF) relays. Threshold-selection DF re…
Incremental selective decode-and-forward relaying for power line communication
A. Dubey, C. Kundu, T. M. N. Ngatched +2
