On synchronisation for SC-FDMA waveform over GEO satellite networks

Single Carrier FDMA may offer important advantages for satellite networks, for instance in terms of increased spectral efficiency, compared to classic MF-TDMA multiple access schemes. This work studies the performance of synchronization procedures and provides indications on the system sizing when SC FDMA is employed over the return link of a GEO satellite system. It is shown how a DVB-RCS like closed loop synchronization can yield satisfactory results for stationary users, while it is still challenging to achieve the same results for mobile terminals.
