hi everybody,
so far I'm working upon a GNURadio implementation of one of the functional block of the DVB-t standard, the "Inner interleaver",
my trouble in this moment is that such functional block needs to perform a permutation on a 1512-bits length chunk:
i've tried to modify the step of this loop, this way:
STEP=1512;
for (int i= 0, i<= noutput_items, i+=STEP)
for (int w= 0, w<= 1511, w+=1) out[i+w]=..
but this doesn't seem to work properly. ( I guess because I'm trying to reference items too far away from my current position in the stream).
another thing i've tried is:
for (int i= 0, i<= noutput_items, i+=1)
for (int w= 0, w<= 1511, w+=1) out[1512*i+w]=...
but this even segfaults at runtine.
which is the wise way I should do interleaving on such big chunks in GNURadio?
thank you guys,
and best regards
