WebWe use the DVB-S2/S2X waveform, which is the most spectrally-efficient available. DVB-S2/S2X provides two to three times the throughput of Viterbi/Reed-Solomon, and it can also be switched to a standard throughput rate, but using a much lower transmission power level. WebThese waveforms were used in many DVB-T performance tests carried out in the laboratory, a summary of which is presented in the next section. A more complete compilation of results can be found in [7]. The pulse spacing in Table 1 is uniformly distributed and is expressed as a mid-range value plus or minus a “dither” factor. ...
