WebThe DVB-S2 standard also allows the adaptation of the transmission scheme to the channel conditions thanks to Variable or Adaptive Coding and Modulation (VCM or ACM) offering consequently a better margin management and throughput increase. WebFig. 1 BER as a function of S/N For this reason, this pplication notea describes a second, viable approach to generating a defined BER, taking into account S /N deterioration: White noise of a defined power is superimposed on the DVB signal. From the noise and the modulated DVB signal, the S/N respectively the C/N ratio in dB (with
