A carrier offset correction scheme based on Maximum Likelihood (ML) method for the downlink of an Orthogonal Variable bit rate Multicarrier-CDMA (MC-CDMA) scheme in a fast frequency selective Rayleigh fading channel is proposed and discussed. The proposed methodology assumes perfect knowledge of phase offset, whereas an Equal Gain Combining (EGC) scheme is considered for MC-CDMA detection. Results in terms of minimum mean square error of the residual carrier frequency offset will be presented.
