Hello all,

 I was wondering if in order to use the DVB-S2  BCH and LDPC encoder I
would have to use the header, scrambler, DVB-S2X modulator and physical
layer frame blocks in my Tx side. In other words, can I use the FEC
encoders from  DVB-S2 stand alone? Also, is the data coming out from the
DVB-S2 LDPC encoder symmetric, that is it has the information bits first
then the parity bits? I'm currently trying to decode the data coming from
the BCH/LDPC encoded data without any of the other blocks and have not been
seeing the results I expect.


Thanks,
Jose
