In this paper, we introduce several technologies to adapt orthogonal frequency division multiple access (OFDMA) scheme to satellite environments. Maximizing the commonalities with the terrestrial system is one of the most important factors for cost-effective service delivery, which will finally bring successful deployment of the system. For this purpose, we adopt an orthogonal frequency division multiplexing (OFDM) based radio interface. At the same time, the interface should be tailored in order to compensate a long round trip delay of satellite systems. In this paper, we present a number of satellite specified techniques which was developed for this purpose, including coordinated multi-point transmission, random access technique, and interleaving technique combined with adaptive modulation and coding. We also discuss the related standardization activities. This electronic document is a "live" template.
