Abstract: PCT No. PCT/EP94/00374 Sec. 371 Date Jun. 27, 1996 Sec. 102(e) Date Jun. 27, 1996 PCT Filed Feb. 10, 1994 PCT Pub. No. WO95/22209 PCT Pub. Date Aug. 17, 1995The 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 +E,uns eta +EE '(D) provided by means for extracting interference signals (83), said interference signals +E,uns eta +EE '(D) being obtained from said input signals and output signals +E,cir +E,uns b+EE +EE (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).
