This work presents a turbo multiuser detector for turbo-coded DS-CDMA systems, which is based on the utilization of parallel interference cancellation scheme and antenna diversity in the receiver in a wireless rich-scattering block fading channel.

Abstract

This work presents a turbo multiuser detector for turbo-coded DS-CDMA systems, which is based on the utilization of parallel interference cancellation scheme and antenna diversity in the receiver in a wireless rich-scattering block fading channel. Multiple access interference effects are naturally reduced by antenna diversity, and, successively, completely eliminated by a single turbo cancellation iteration. The proposed turbo-PIC detector is shown, highlighting its remarkable performance in term of BER: particularly, we stress the low complexity required to suppress MAI and achieve excellent results, also in the block fading environment where the high correlation value strongly limits the single user bound.
