Blind identification schemes for multi-channel DS/SS systems (original) (raw)

Preliminary results on new blind equalization schemes for Direct-Sequence/Spread-Spectrum (DS/SS) signals are presented. These schemes are based on previously proposed subspace algorithms. Signi cant improvements over previous blind identi cation schemes can be gained by explicitly exploiting the structure of the DS/SS signals, thus reducing the number of parameters that need to be estimated. The results presented focus on a simple single-user system, but are easily extensible to multiple-user systems.
