In this paper, an MC-CDMA system using wavelet modulation technique for encoding communication data into signals is introduced. Comparative bandwidth evaluations of these waveform codings are analyzed by using various wavelet sets. From the simulation results, we conclude that this wavelet based encoding scheme with fine time-frequency localization property can greatly improve the bandwidth efficiency of an MC-CDMA.
