Secrecy Rates for Relay Selection in OFDMA Networks

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.
