  • 초록

    Current studies based on the DVB-S2x standard for the next-generation multi-beam HTS/BH satellite have been investigated. To enhance the efficiency of the transmission throughput and maximize the utilization of the satellite payload resources and bandwidth, the concepts of two advanced techniques, namely, precoding and BH, are described. Furthermore, state-of-the-art aspects currently under discussion, and future study items in the DVB TM-S standardization group, are summarized in this article.
