N2 - In this paper a new combined acquisition and detection scheme for a multiuser communications system is presented. The goal of this scheme is not only the minimization of multiuser interference in the detection, but also to minimize multiuser effect in the acquisition stage. The acquisition and tracking problems are both solved with the multiresolutive adaptive structure. Once the receiver is synchronized, a detector scheme estimates the interfering subspace to minimize its influence. This information is fedback and helps the acquisition scheme to minimize the effect of multiuser interference.
