Zero correlation zone sequences for multi-carrier DS-CDMA systems

A multi-carrier DS-CDMA system is proposed that employs zero correlation zone (ZCZ) sequences as spreading sequences to reduce the multipath interference. Bit error rates (BER) and frame error rates (FER) for a range of E/sub b//N/sub 0/ values are presented. It is demonstrated that the proposed scheme can improve the BER and FER performance, in the frequency selective fading channel evaluated, when a single correlator receiver is used on each sub-carrier.
