摘要：

The goal of a blind two-dimensional (2-D) RAKE receiver for DS-CDMA is to cancel strong multiuser access interference (MUAI) while optimally combining the signal of interest's (SOI) multipath. The weight vector yielding the optimum SINR for bit decisions may be computed as the "largest" generalized eigenvector of a matrix pencil composed of the SOI pins MUAI and MUAI alone space-time correlation matrices. An alternative blind 2-D RAKE receiver is presented based on RLS-type space-time adaptive filtering that offers competitive performance. The applicability of the scheme to the IS-95 uplink is addressed.
