Abstract :
In orthogonal frequency division multiplexing (OFDM) relay system, subcarrier mapping at the relay has been shown to substantially improve the performance evidently. In this paper, we investigate the performance analysis of dual-hop OFDM relay systems with subcarrier mapping over Nakagami-m fading channels. A closed-form expression of outage probabilty is derived for Amplify-and-Forward OFDM Relay System with subcarrier mapping. The efficiency of the analytical performance is demonstrated through simulation results.
