Dalam makalah ini, kami mencadangkan skim anggaran berasaskan aktiviti untuk menentukan perbezaan kuasa isyarat yang diterima, yang meningkatkan prestasi BER skim SIC dalam sistem DS/CDMA dengan mengambil kira faktor aktiviti suara yang praktikal, dan membandingkan prestasi BER dengan yang lain. skim dengan atau tanpa anggaran. Keputusan analisis berangka menunjukkan bahawa skema SIC dengan anggaran berasaskan aktiviti yang dicadangkan meningkatkan prestasi BER berbanding dengan itu tanpa mengambil kira aktiviti suara, dan ia mendekati anggaran ideal apabila jumlah pengguna serentak meningkat. Di samping itu, semakin tinggi menjadi SNR maksimum yang boleh dicapai, semakin baik prestasi BER bagi skim anggaran berasaskan aktiviti yang dicadangkan.

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.
