Abstract :
In this paper, we studied multicode multicarrier code division multiple access (MC-MC-CDMA). We proposed a linear minimum mean square error (LMMSE) multiuser detector for this system. MC-MC-CDMA system can support multirate transmission. In addition, it is resistant to frequency selective fading. We have simulated MC-MC-CDMA and compared it with multicode single carrier (MC-SC) CDMA system. The simulation results show that the former system is better than the later one in frequency selective fading channel. Then, we will derive the analytical bit error rate (BER) of the system.
