%X A novel CDMA BLAST space-time code technique is proposed in this paper for the down link in a cellular CDMA system. Scrambling codes and orthogonal spreading codes are employed to identify different transmit antennas and different users, respectively. Due to good auto- and cross-correlation proprieties of the scrambling codes, the proposed scheme can obtain considerable improvement in the bit error rate performance without sacrifice of the precious orthogonal code resources.
