Abstract

Abstract: A new method which use the Kalman filter as the Rayleigh flat fading channel estimator is presented, and the performance analyses of decorrelator,two-stage detector and decision-feedback detector with the channel estimator are conducted.The simulated results show the performance of two-stage detector and decision-feedback detector is better than that of decorrelator in low SNR region, but for high SNR,the former have higher bit error rate.

Key words: code division multiple access, multiuser detection, channel estimation
