Untuk mengurangkan lagi kadar penghantaran isyarat penyiaran satelit berbilang saluran, yang nisbah pembawa-ke-bunyinya (CNR turun naik disebabkan pengecilan hujan, kami mencadangkan penghantaran semula optik berasaskan radio-over-fiber (DRoF) yang didigitalkan. sistem berdasarkan pemampatan kombinasi penyesuaian untuk isyarat penyiaran satelit (BS)/satelit komunikasi (CS) definisi ultra-tinggi (UHD). Sistem yang dicadangkan mengurangkan kadar penghantaran semula optik isyarat BS/CS sebanyak mungkin semasa mengendalikan input Turun naik CNR. Oleh itu, kadar penghantaran isyarat komunikasi dalam penghantaran pemultipleksan pembahagian masa (TDM) dipastikan, dan perkongsian rangkaian isyarat komunikasi dan isyarat penyiaran melalui rangkaian optik pasif (PON) direalisasikan. Berdasarkan ITU-R P. Model ramalan 618-13, penilaian percubaan dilakukan menggunakan anggaran statistik jangka panjang pengecilan akibat hujan. Pengecilan dinilai sebagai peratusan masa perkhidmatan penghantaran semula jangka panjang tersedia. Ditunjukkan bahawa sistem yang dicadangkan mampu menampung pelbagai pengecilan hujan dan mencapai peratusan masa 99.988% untuk tempoh penyediaan perkhidmatan. Untuk menunjukkan kesan pengurangan kadar sistem yang dicadangkan, kesan pengurangan bit kuantisasi sebagai fungsi input CNR, yang bergantung pada pengecilan hujan, disahkan secara eksperimen. Eksperimen menunjukkan bahawa masa operasi perkhidmatan sebanyak 99.978% boleh dicapai dengan penghantaran 3-bit. Ini bermakna pengurangan 62.5% dalam kadar penghantaran direalisasikan berbanding dengan pengkuantitian tetap konvensional. Tambahan pula, purata nombor bit pengkuantitian dalam sistem kami untuk masa operasi perkhidmatan ialah 3.000, menunjukkan bahawa kebanyakan masa operasi perkhidmatan diliputi oleh penghantaran 3-bit sahaja.

Abstract: In order to further reduce the transmission rate of multi-channel satellite broadcast signals, whose carrier-to-noise ratio (CNR fluctuates due to rainfall attenuation, we propose a novel digitized radio-over-fiber (DRoF) -based optical re-transmission system based on adaptive combination compression for ultra-high definition (UHD) broadcasting satellite (BS)/communications satellite (CS) broadcast signals. The proposed system reduces the optical re-transmission rate of BS/CS signals as much as possible while handling input CNR fluctuations. Therefore, the transmission rate of communication signals in time-division multiplexing (TDM) transmission is ensured, and network sharing of communication signals and broadcast signals via passive optical network (PON) is realized. Based on the ITU-R P.618-13 prediction model, an experimental evaluation is performed using estimates of the long-term statistics of attenuation due to rainfall. The attenuation is evaluated as a percentage of the time that long-term re-transmission service is available. It is shown that the proposed system is able to accommodate a wide range of rainfall attenuation and achieve a 99.988% time percentage for the duration of service provision. In order to show the rate reduction effect of the proposed system, the quantization bit reduction effect as a function of the input CNR, which depends on rainfall attenuation, is experimentally confirmed. Experiments show that service operation time of 99.978% can be achieved by 3-bit transmission. This means a 62.5% reduction in transmission rate is realized compared to conventional fixed quantization. Furthermore, the average quantization bit number in our system for service operation times is 3.000, indicating that most service operation times are covered by just 3-bit transmission.
