Tiivistelmä
This thesis compares the Fifth Generation New Radio (5G NR) standard in Non-terrestrial Networks (NTN) and Digital Video Broadcasting (DVB) standards Second Generation Satellite Extensions (S2X) and Return Channel via Satellite 2 (RCS2). The intent of this work is to help understand the operational conditions and system architectures the technologies can operate in, the functionalities they offer and how the technologies perform in said conditions and architectures.
This thesis is divided into three sections. The first section provides background on the operation of 5G NR and its extension to NTN. The second section is about the DVB-S2 standard with its extensions as well as the DVB-RCS2 standard. The final section compares the technologies in regard to their operational conditions, functionalities and respective performance. Initial simulation results are used to aid in performance analysis. The two simulators implement systems conforming to the 5G NR and DVB-S2X/RCS2 standards.
In the thesis it is observed that existing research directly comparing the technologies is scarcely available and there is a clear need for further research. Also, developing the simulations further is necessary in making reliable conclusions about the performance of the technologies, since the simulation results are only initial and not comprehensive enough for definitive conclusions. According to the comparison done, 5G NR NTN is better suited to mobile communication and supports a greater number of functionalities than DVB-S2X/RCS2. Both technologies can operate in similar operational conditions. 5G NR supports more varied system architectures but both technologies support the same satellite-based systems. Existing research and the initial simulation results seem to support the claim that the DVB-S2X standard performs slightly better than 5G NR NTN in fixed satellite communication. Existing research would seem to indicate that 5G NR performs slightly better than DVB-RCS2.
