摘要：

This paper presents the advantages and disadvantages of a multicarrier code-division multiple-access (MC-CDMA) system. The transmitter/receiver structure and the bandwidth of transmitted signal spectrum are compared with those of a conventional, direct-sequence (DS) CDMA system, and an MC-CDMA design method, how to determine the number of subcarriers and the length of guard interval is discussed. The bit error rate (BER) lower bounds for DS-CDMA. and MA-CDMA systems are derived and their equivalence is theoretically demonstrated, Finally, the BER performance in downlink and uplink channels with frequency-selective Rayleigh fading is shown by computer simulation.
