Abstract

This paper discusses the performance of multicarrier CDMA technique for the next generation mobile communication system. The transmitter/receiver structure and the bandwidth of transmitted signal spectrum are analysed for the proposed systems. It defines MC-CDMA as a frequency PN pattern and MC-DS-CDMA as a straight extension of DS-CDMA; and argues that these twin asymmetric technologies are most suitable for 4G since MC-CDMA is suitable for the downlink and MC-DS-CDMA is suitable for the uplink in the cellular systems. Although MC-CDMA performs better than MC-DS-CDMA, it needs chip synchronization between users, and is therefore difficult to deploy in the uplink. Finally, the BER performance in downlink and uplink channels is shown by computer simulation.
