Performance analysis of cooperative OFDM network with ordered subcarrier pairing

In cooperative OFDM networks, ordered subcarrier pairing (OSP) at the relay has been shown to improve the average end-to-end capacity evidently. In this paper, the statistical performance evaluations are provide for two-hop OFDM relay link with both amplify-and-forward (AF) and decode-and-forward (DF) protocol. First, closed-form expressions are derived for the probability density function (PDF) of the signal-to-noise ratio (SNR) of the mapped subcarrier pair link. Second, the performance of average symbol error probability (SEP) is given. The efficiency of the analytical performance is demonstrated through simulation results.
