Dans cet article, nous proposons un schéma d'estimation basé sur l'activité pour déterminer la disparité de puissance du signal reçu, qui améliore les performances du BER du schéma SIC dans un système DS/CDMA en considérant un facteur d'activité vocale pratique, et comparons les performances du BER avec celles d'autres systèmes. schémas avec ou sans estimation. Les résultats de l'analyse numérique montrent que le schéma SIC avec l'estimation basée sur l'activité proposée améliore les performances du BER par rapport à celle sans tenir compte de l'activité vocale, et qu'il se rapproche de celui de l'estimation idéale à mesure que le nombre total d'utilisateurs simultanés augmente. De plus, plus le SNR maximum atteignable est élevé, meilleures sont les performances du BER du schéma d'estimation basé sur l'activité proposé.

Abstract: In this paper, we propose an activity-based estimation scheme to determine the received signal power disparity, that enhances the BER performance of the SIC scheme in a DS/CDMA system considering a practical voice activity factor, and compare BER performance with those of other schemes with or without estimation. Numerical analysis results show that the SIC scheme with the proposed activity-based estimation improves the BER performance compared with that without considering voice activity, and it approaches to that of the ideal estimation as the total number of concurrent users increases. In addition, the higher becomes the maximum attainable SNR, the better becomes the BER performance of the proposed activity-based estimation scheme.
