Performance Analysis of Decode-and-Forward System

For cooperative system, in which eavesdropper can be anywhere, so it may overhear information through both source and relay’ transmission . In this letter, we evaluate the secrecy performance of decode-and- forward (DF) system with both the optimal relay selection (ORS) and the conventional relay selection (CRS) schemes, and the closed expression on the secrecy outage probability(SOP) of two schemes are derived; The derivations are confirmed through Monte Carlo simulations.
