Dans cet article, la technique d'amélioration d'un récepteur à annulation d'interférence parallèle (PIC) non linéaire pour un système DS-CDMA est étudiée, qui annule uniquement l'interférence d'accès multiple (MAI) estimée d'utilisateurs spécifiques à chaque étage du récepteur. Cette technique a été introduite en tant que récepteur PIC utilisant une décision dure de zone nulle dans le déroulement de l'IEEE MILCOM '94, mais les résultats numériques n'ont pas été entièrement fournis avec des seuils de décision variables. Dans cet article, les performances du récepteur PIC utilisant la décision dure de zone nulle sont présentées dans un canal à évanouissement de Rayleigh. De plus, un nouveau récepteur PIC avec un seuil de décision adaptatif est proposé. Dans le nouveau récepteur PIC proposé, le seuil de décision pour l'annulation partielle est ajusté en fonction des statistiques de ses sorties de filtre adapté (MF). Le BER du récepteur PIC proposé est obtenu par simulation et comparé à ceux du récepteur PIC conventionnel et du récepteur PIC utilisant une décision dure de zone nulle dans un canal à évanouissement de Rayleigh. Il est démontré que le récepteur PIC proposé atteint de meilleures performances que le récepteur PIC conventionnel et que le récepteur PIC utilisant une décision dure de zone nulle dans un canal à évanouissement de Rayleigh.

Abstract: In this paper, the improvement technique for a nonlinear parallel interference cancellation (PIC) receiver for a DS-CDMA system is studied, which cancels only the estimated multiple access interference (MAI) from specific users at each receiver stage. This technique was introduced as a PIC receiver using null zone hard decision in the proceeding of IEEE MILCOM '94, but the numerical results has not been fully provided with varying decision threshold. In this paper, the performance of the PIC receiver using null zone hard decision is shown in a Rayleigh fading channel. Also, a new PIC receiver with an adaptive decision threshold is proposed. In the proposed new PIC receiver, the decision threshold for partial cancellation is adjusted according to the statistic of its matched filter (MF) outputs. The BER of the proposed PIC receiver is obtained by simulation and compared with those of the conventional PIC receiver and the PIC receiver using null zone hard decision in a Rayleigh fading channel. It is shown that the proposed PIC receiver achieves better performance than the conventional PIC receiver and the PIC receiver using null zone hard decision in a Rayleigh fading channel.
