8.10 Data Rate Range
Symbol Rate and Data Rate Range for DVB-S2, DVB-S and DVB-DSNG. There is some
roundoff in the data rate ranges in the last digit. Table 8-1 is for the standard FEC frame, and
Table 8-2 is for the short frame. The tables are based on a 188-byte transport stream packet.
When a 204-byte frame size is selected, the data rate increases by 204/188.
DVB recommends turning the Pilot ON for 8PSK and higher modulation orders, particularly
when phase noise is present.
The following modes may need Pilot ON for low C/N operation: 8PSK 1/2, 16APSK 2/3 and 3/4,
and 32APSK 3/4 to assist carrier recovery.
QPSK 1/4, 1/3, and 2/5 data is for information only.
