This letter investigates an effect of diversity techniques on the performance of OFDM-CDMA based broadband wireless access networks and evaluates the maximum achievable diversity gain for a two-path Rayleigh fading environment. Simulation results show that the OFDM-CDMA system applying a space-time-frequency diversity with a full-rate full diversity code can give the diversity of D=4 and D=8 for both multi-user cases of maximum user and half user capacities, respectively.
