Abstract
The present invention concerns an apparatus and method for reducing the
multiuser-interference of input signals. The apparatus in accordance with the
present invention comprises a multivariate predictor (81) and a decision
quantizer (82), said multivariate predictor (81) operating on interference
signals $\underline{\eta}'(D)$ provided by means for extracting interference
signals (83), said interference signals $\underline{\eta}'(D)$ being obtained
from said input signals and output signals $\underline{\hat{b}} (D)$ which are
available at an output of said decision quantizer (82) and fed back from there
to said means for extracting interference signals (83).
