Wireless Powered Cooperative Jamming for Secure OFDM System
Wireless Powered Cooperative Jamming for Secure OFDM System
This paper studies the secrecy communication in an orthogonal frequency division multiplexing (OFDM) system, where a source sends confidential information to a destination in the presence of a potential eavesdropper. We employ wireless powered cooperative jamming to improve the secrecy rate of this system with the assistance of a cooperative …
