PILOTS
In order to expedite carrier recovery, the standard allows two operating modes for
each modulation type: Pilot-less (i.e. no Pilot symbols are inserted) and Piloted,
where Pilot symbols are inserted to aid carrier synchronization. The Pilots menu
enables to choose between the two operating modss.
