I am not a signal expert, not at all, but wouldn't it be better to rename
QPSK_8 to 8PSK and QPSK_B to BPSK? (and accordingly FE_CAN_..)
http://en.wikipedia.org/wiki/DVB-S2 also mentions higher PSK-modulations.
As this is a good chance we might also consider adding the additional
DVB-H parameter (taking the additional TPS-values into account)?
What about the problems discussed last week about the hierarchy-parameter
and the selection of LP and HP streams (+ ALPHA value) for DVB-T/H?
IIRC, during the discussion in November someone also mentioned, that
DVB-S2 also support hierarchical transmissions...
