Abstract
Recently the extension of the digital video broadcasting second generation standard for transmission over satellite (DVB-S2) has been finalized in order to achieve a higher spectral efficiency without introducing fundamental changes to the complexity and structure of the common DVB-S2 standard. Therefore, this extension is termed DVB-S2X. In this paper, we focus on a more powerful physical layer frame structure, known as Super-Frame (SF), which has been adopted as optional waveform container in Annex E of the DVB-S2X specification. The paper provides insights to capabilities of the SF structure in support of emerging system applications.. Analytical results of the SF performance are complemented by the performance results obtained from an end-to-end testbed implementing SF format 4, which is optimized for wideband transmission and very low SNR reception conditions. The testbed includes prototype design of modulator and demodulator featuring the SF generation and detection capability. The prototype devices are able to operate at a wide range of signal-to-noise ratios and at high symbol rates. This design represents the basis for planned over-the-air tests using a single wideband satellite transponder to demonstrate the feasibility of transmitting and receiving 1 Gbit/s.
