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 (LS_kD + 1) + σ ^M_{m = 1} min(LS_kR_m + 1, LR _mD + 1) is available, where M is the number of relays, and LS _kD + 1, LS_kR_m + 1, and LR_mD + 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.
