Abstract

This paper investigates the Parallel Interference Cancellation technique in Direct Sequence Optical Code Division Multiple Access (ds-ocdma) system. In the proposed system, the estimated interference is removed from the received signal. We have developped a new approach to obtain the analytical expression of error probability in chip synchronous case, for Optical Orthogonal Codes (ooc). We have shown that under specific conditions between codes parameters and users’ number, the interference can be completely neutralized. Simulation results have validated the theoretical analysis. It is shown that the proposed receiver is effective in reducing significantly the effects of Multiple Access Interference (mai) compared to other interference cancellation systems.

Résumé

Cet article présente l’étude d’un récepteur basé sur l’annulation parallèle d’interférence d’accès multiple dans un système d’accès multiple par répartition en code à séquence directe (ds-ocdma). Le principe consiste à estimer l’interférence due aux utilisateurs non désirés pour la soustraire du signal reçu à l’entrée du récepteur. Nous avons obtenu la formule théorique de la probabilité d’erreur dans le cas synchrone, pour les codes optiques orthogonaux (ooc). Nous avons prouvé que, pour des conditions spécifiques concernant les paramètres des codes et le nombre d’utilisateurs, l’effet de l’interférence peut être complètement éliminé Les résultats de simulation ont validé l’analyse théorique. On montre enfin que le récepteur proposé est plus efficace que d’autres systèmes d’annulation d’interférence pour réduire de manière significative les effets de l’interférence d’accès multiple (mai).
