MC - CDMA system based on CMFB
XU Rong-qing · Ha'erbin gongye daxue xuebao · 2004
A 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 svstem based on CMFB was constructed. The perfect re-construction condition of M - band filter banks and M - band transmultiplexer provides a multi-carrier modula-tion method based on the M - band filter banks. A fast arithmetic of the multi-carrier modulation based on CMFB and the complement of the arithmetic was given. Simulation results indicate that MC - CDMA based on CMFB is better than OFDM MC - CDMA.
