Abstract: A new multi-code multicarrier code division multiple
access (MC-MC-CDMA) system is proposed and analyzed in a frequency selective
fading channel. By allowing each user to transmit an M-ary code sequence, the
proposed MC-MC-CDMA system can support various data rates as required by next
generation standards without increasing the interference which is common in
general multicarrier CDMA systems. The bit error rate of the system is
analytically derived in frequency selective fading, with Gaussian noise and
multiple access interference. The results show that the proposed MC-MC-CDMA
system clearly outperforms both single-code multicarrier CDMA (MC-CDMA) and
single-carrier multicode CDMA in a fixed bandwidth allocation. This indicates
that MC-MC-CDMA can be considered for next generation cellular systems.
