Abstract

Blind deterministic receivers for DS-CDMA systems based on the PARAFAC model have been proposed in several papers since their conception in. In many cases, the transmitted signals can be considered uncorrelated. Hence, we develop PARAFAC receivers for uncorrelated signals. We introduce several numerical algorithms for orthogonality constrained PARAFAC on which receivers for uncorrelated signals can be based. Simulation results show an increase in performance when the PARAFAC receiver takes the uncorrelatedness of the transmitted signals into account.
