Abstract Multi Carrier Code Division Multiple Access (MC-CDMA) is a suitable modulation method for high data rates. In this modulation system, using of combining methods are inevitable for restoring orthogonality between diverse user signals. In this paper, the combining techniques of a MC-CDMA based on lifting discrete wavelet transform strategy (LDWT) are studied. Is presented to keep up the symmetry against the multipath Flat Fading Channels (FFC). Show of MC-CDMA under many channels similar the AWGN channel and FFC, is examined and BER versus SNR graphs are plotted and their presentation is deliberate.
