- In this paper, we deal with robust initial access scheme in spread spectrum mode for mobile DVB-RCS2 standard. For log-on process, it should be effective in terms of rapidity and reliability if we can utilize robust transmission and reception schemes under large timing and carrier frequency offset as well as very low SNR. Firstly, after we review the log-on burst transmission related with spread spectrum of DVB-RCS2 specification under the harsh channel condition, we come up with the DVB-RCS2 tailored scheme that VSAT terminals should be able to support the reference waveforms. It's expected that it's applicable adaptively depending on channel condition to be considered.
