Abstract
In this paper, we investigate the performance of a cooperative orthogonal frequency-division multiple-access (OFDMA) system with decode-and-forward (DaF) relaying. Specifically, we derive a closed-form approximate symbol-error-rate expression and analyze the achievable diversity orders. Depending on the relay location, a diversity order up to (L-SkD + 1) + Sigma(M)(m=1) min(L-SkRm + 1, L-RmD + 1) is available, where M is the number of relays, and L-SkD + 1, L-SkRm + 1, and L-RmD + 1 are the lengths of channel impulse responses of source-to-destination, source-to-mth relay, and mth relay-to-destination links, respectively. Monte Carlo simulation results are also presented to confirm the analytical findings.
