This paper presents an investigation of transmission technologies for beyond IMT-2000 satellite systems. Because a satellite link has longer round trip delay than a terrestrial link, we need technologies that would make the satellite component especially efficient. By analyzing the main features of the satellite component of the IMT-2000 systems, we suggest desirable modifications for the application to beyond 3G system. We also demonstrate simulation results of a few new radio access technologies including adaptive coding with H-ARQ, STTD, indicating these can provide enhanced performance in mobile satellite channels. In addition, not only to increase the performance but also to keep commonalities between terrestrial standards, more advanced transmission technologies including multi-carrier transmission, interference cancellation, and highly efficient modulation and coding should be investigated in more detail.
