Multiple access interference (MAI) is a key problem in DS-CDMA systems. Both multiuser detectors and array antennas have been introduced to reduce the effect of MAI. Many existing multiuser detectors require so many system parameters and their adaptive versions require a training sequence. These parameters are difficult to obtain in multipath fading channels. A novel blind space-time multiuser detector based on the Kalman filter is proposed. With numerical simulations and performance analysis, it is shown that the detector is ahead of other existing detectors in eliminating MAI and near-far resistance. Furthermore, it can converge rapidly.
