BER performance analysis of multicarrier-CDMA systems in multipath fading channel

摘要

This paper presents the BER analysis of the asynchronous Multicarrier (MC)-CDMA system in multipath fading channel. We derive the BER of the MC-CDMA and compared with that of the DS-CDMA. We found that the BER of the MC-CDMA is a little worse than that of the band-limited DS-CDMA under the same bandwidth and the same spreading factor, and when the number of multipath is infinity, the BER of both systems are regarded as being that for the case without fading channel. However, if the number of multipath is more than the number of finger of Rake receiver, the MC-CDMA system can perform better than the DS-CDMA system.
