Thanks Achilleas Thanks Eric,
Yes Achilleas, what you have described is right exactly what I need.
the constant permutation is indeed a vector hard coded in my block.
my problem is that I could neither set the step of the cycle
for (int i = 0; i < noutput_items; i+= STEP){
as far as 1512, nor as far as 6048.. (well'if I do it runs but the
output has no meaning)
another thing I've tried is to demultiplex my input stream into many
output streams in order to do interleaving among them, but I don't think
it's a good idea.. and actually works only as far as 1512.
Yesterday I realized how to do that by passing just big vectors to my
block but I'm still failing to get it to work on vectors longer than
1512 bytes.. :)
what I'm working upon is a dvbt transmitter, as described in
http://www.com-tech.it/downloads/en_300744.pdf
I'm (slowly, because I also have to keep up with my academic duties)
climbing up the functional block chain towards the aerial.. :D
so where I think I am now is the Inner Interleaver..
very many thank for listening
