摘要：
We describe a chip correlation MMSE receiver with multipath interference correlative timing (MICT) for downlink direct-sequence code-division multiple access (DS-CDMA) systems. The receiver can be implemented easily, and analysis shows that the proposed method can obtain a chip correlation matrix that is about 50-times faster than the covariance matrix in W-CDMA systems, and the bit error rate (BER) performance of the receiver is the same as that of conventional maximum likelihood detectors (MLDs), operating under ideal conditions. Further, computer simulations showed that the BER performance maintained a good performance even in fast fading environments.
