Abstract :
Blind multiuser detection employs linear adaptive filters to produce a decision variable with improved signal to interference ratio. In this paper, we employ linear adaptive filters on each user´s signal before the decision variables are input to either a decorrelator or a multistage detector to improve the bit error rate performance compared to simply using the decorrelator or multistage detector without adaptive filtering.
