A novel adaptive Fast Frequency Hopping based MC-DS/CDMA is proposed to improves the performance in the frequency selective fading channel. The FH/MC DS-CDMA scheme achieves the diversity gain the frequency diversity gain as well as the time diversity gain.  The proposed system can achieve the frequency diversity gain provided by Fast Multi-carrier hopping, and the proposed system creates the time diversity gain with maximum ratio combining (MRC) at the Rake receiver. Therefore, the performance of this Fast FH MC-DS/CDMA is improved compared to the conventional MC-CDMA in the frequency selective fading channel.
