This paper presents a Turbo Multiuser Detector for Turbo-Coded DS-CDMA systems, based on the utilization of a PIC and a bank of turbo decoders, in which the PIC performs interference cancellation after each constituent decoder of the turbo decoding scheme. Moreover, we propose a new enhanced estimator of the signal-to-noise-plus-interference-ratio used in the decision device and in the MAP decoding algorithm. By means of computer simulations, we will show that the proposed receiver outperforms other similar schemes for medium to very high system loads, in AWGN channel.

Abstract

This paper presents a Turbo Multiuser Detector for Turbo-Coded DS-CDMA systems, based on the utilization of a PIC and a bank of turbo decoders, in which the PIC performs interference cancellation after each constituent decoder of the turbo decoding scheme. Moreover, we propose a new enhanced estimator of the signal-to-noise-plus-interference-ratio used in the decision device and in the MAP decoding algorithm. By means of computer simulations, we will show that the proposed receiver outperforms other similar schemes for medium to very high system loads, in AWGN channel.
