Blind asynchronous near-far resistant FIR receivers for CDMA communication

Abstract

A canonical structure of near-far resistant FIR receivers for asynchronous CDMA over ISI channels is proposed. The receiver structure includes a minimum-order FIR decorrelator and a bank of equalizers designed for each user. An equivalence between the decorrelator and the so-called statistical decorrelator is established, which leads to a blind near-far resistant FIR receivers based on decorrelating (second-order or higher-order) statistics.
