Abstract

In this paper blind multiuser detection of Direct Sequence Code Division Multiple Access (DS-CDMA) signals over time-varying time-dispersive channels is considered. A number of methods for multiuser detection over time-dispersive channels have been proposed in previous research. It is shown in this paper that in a time-varying channel these methods will not perform satisfactorily and an adaptive multiuser detector for time-varying channels based on the Interacting Multiple Models estimator is proposed. It is shown by simulations that the proposed method outperforms the existing ones in a time-varying channel.
