An M-band CMFB with a side lobe of about 45 dB was designed using the optimum equal wave method. Modulation was made with the updated comprehensive filter banks, and demodulation was made with the analytic filter banks, and a multi-carrier CDMA system based on CMFB was constructed. The perfect reconstruction condition of M-band filter banks and M-band transmultiplexer provides a multicarrier modulation method based on the M-band filter banks. A fast algorithm of the multi-carrier modulation based on CMFB and the complementation of the algorithm was given. Simulation results indicate that MC-CDMA based on CMFB is better than OFDM MC-CDMA.
