A channel coding scheme for an orthogonal multicarrier DS-CDMA system is suggested. The scheme does not reduce the transmission rate of information nor increase the transmitted signal bandwidth of the uncoded multicarrier system. Simulation results for the suggested scheme in a multipath fading channel show considerable coding gain over the uncoded case.
