Prestasi tahap sistem sistem penyiaran berkod superposisi/sistem tindanan perkhidmatan unicast dipertimbangkan. Rangkaian selular untuk perkhidmatan unicast sahaja dianggap sebagai sistem terhad gangguan, di mana peningkatan kuasa penghantaran tidak membantu meningkatkan daya pemprosesan rangkaian terutamanya apabila faktor penggunaan semula frekuensi menghampiri 1. Dalam kes sedemikian, jumlah kuasa yang tidak menyumbang kepada peningkatan daya pengeluaran boleh dianggap sebagai "tidak digunakan." Keadaan ini mendorong kami untuk menggunakan kuasa yang tidak digunakan untuk perkhidmatan penyiaran, yang boleh disediakan dengan cekap dalam rangkaian frekuensi tunggal berasaskan OFDM seperti dalam sistem penyiaran multimedia digital. Dalam kertas kerja ini, kami menyiasat prestasi sistem tindanan siaran/unicast sedemikian di mana perkhidmatan siaran frekuensi tunggal ditindih ke atas perkhidmatan selular unicast. Pemultipleksan perkhidmatan alternatif menggunakan FDM/TDM juga dipertimbangkan untuk perbandingan.

Abstract: The system level performance of a superposition coded broadcast/unicast service overlay system is considered. Cellular network for unicast service only is considered as interference limited system, where increasing the transmission power does not help improve the network throughput especially when the frequency reuse factor is close to 1. In such cases, the amount of power that does not contribute to improving the throughput can be considered as "unused." This situation motivates us to use the unused power for broadcast services, which can be efficiently provided in OFDM based single frequency networks as in digital multimedia broadcast systems. In this paper, we investigate the performance of such a broadcast/unicast overlay system in which a single frequency broadcast service is superimposed over a unicast cellular service. Alternative service multiplexing using FDM/TDM is also considered for comparison.

AB - The system level performance of a superposition coded broadcast/unicast service overlay system is considered. Cellular network for unicast service only is considered as interference limited system, where increasing the transmission power does not help improve the network throughput especially when the frequency reuse factor is close to 1. In such cases, the amount of power that does not contribute to improving the throughput can be considered as "unused." This situation motivates us to use the unused power for broadcast services, which can be efficiently provided in OFDM based single frequency networks as in digital multimedia broadcast systems. In this paper, we investigate the performance of such a broadcast/unicast overlay system in which a single frequency broadcast service is superimposed over a unicast cellular service. Alternative service multiplexing using FDM/TDM is also considered for comparison.
