In this paper a scheme was proposed to improve the performance form the Bit Error Rate (BER) view point for Multicarrier-Direct-Sequence-Code Division Multiple Access (MC-DS-CDMA) system in wireless channel. The conventional MC-DS-CDMA-system is based on Fast Fourier Transform (FFT). The proposed system was based on Multi-Wavelet transform (MWT). Simulation results are done in three different types of channels. Simulation shows that the proposed system outperforms the conventional system in addition to a coded version of the conventional system. Also the MC-DS-CDMA-system which is based on MWT achieves better performance with the same loss in bandwidth than the MC-DS-CDMA-system based on …
