Object
Dvb-S2 Physical Layer Pilot insertion. When enabled, every 16 slots (of 90 symbols) the modulator will insert 36 unmodulated symbols to aid in receiver synchronization. Set Pilots on in the following cases: - ACM model - High amount of phase noise is present - At low data rates - When distortion is present - When using one of the following MODCODs 8-PSK 3/5 and 2/3, 16-APSK and 32-APSK (due to MODCOD structure).
