Abstract :
In this paper, we investigate OFDM-based selective decode-and-forward (DF) relay systems with ordered subcarrier pairing (OSP). Closed-form expressions for the probability distribution function (PDF) of the signal-to-noise ratio (SNR) on the subcarrier pairs are derived. The outage performance of the systems over both Rayleigh and Nakagami fading channels are analyzed. Monte Carlo simulations validate our analysis.
