ETSI ETSI TR 103 297 V1.1.1 (2017-07) 6 1 Scope The present document aims at assessing the performance of a SC-FDMA-based radio waveform over geostationary satellites in Ku/Ka band.

21、 Moreover, it aims at defining an evaluation framework for performance comparison with existing waveform technologies (e.g. DVB-S2, DVB-S2X and DVB-RCS2), focusing on the radio and physical layers. The present document deals with satellite return link only. The forward link is for further study. For

22、 the return link, two use cases have been identified and treated so far, Satellite News Gathering (DSNG) and Broadband Access. The present document provides a description of the waveforms to be compared; it identifies their key characteristics, defines the system model used for comparison and presen

23、ts comparative performance results in terms of spectral efficiency. A complexity analysis is also performed. 2 References 2.1 Normative references Normative references are not applicable in the present document. 2.2 Informative references References are either specific (identified by date of publica

47、a SC-TDM scheme, 5 % roll-off, with a classical time domain implantation. For this complexity comparison between frequency domain and time domain only the different parts were considered, i.e. waveform generation (transmission, FDT and TDT) and reception equalization (FDE and TDE).
