Abstract :
In this paper, we study the secrecy communication using physical layer security in OFDMA networks. The expressions of secrecy rates and outage probability are derived in OFDMA networks using Decode-and-Forward (DF) strategy. Monte Carlo simulations are carried out to validate our analysis.
