A new spreading scheme is introduced for ifying the multi-access interference(MAI)for CDMA systems. For the synchronous systems, this scheme can keep the orthogonality among the codes used to different users in multipath environments and, therefore, cancel the MAI completely. In alternation, the multi-symbols of a user are overlapped and can, however, be calculated. The simulation shows the effectiveness of this approach for reducing bit error rate(BER) while the system throughputs remain unchanged. In addition, the band efficiency is also discussed.
