MAI-Suppression with Fractional T-equalizer for CDMA

Autoren: K. Knoche, J. Rinas, K.-D. Kammeyer
Kurzfassung: Wideband CDMA systems with orthogonal spreading codes suffer severely due to the loss of orthogonality by multipath propagation. This yields Multiple Access Interference (MAI) which gravely reduces the performance of classical systems with Rake-receivers. In our approach we attempt to restore orthogonality again by using a fractional T-equalizer. The results are compared with a system using the tapped delay line equalizer that works in chip duration and the classical solution for wideband CDMA systems, the Rake-receiver.
