Let’s think about the following auto/cross correlator:
divide because I need to normalize the correlation result.
If we place
null source, or
constant source with value of zero right
pad source, the simplified form of the correlator becomes 0
divided by 0.
time sink right after the
pad sink then, I can see the
hit the infinity. With a simplified flow graph:
Back to the my correlator, how can I handle such
infinity value coming
into the next block?
My guess is that if a source block is a type of float, then
might have a maximum value of float. So, I think I can reject
if (in[i] > threshold), where
threshold is big enough,
correlator it is fine to have a value just larger than one.
Do you think what I guess is right? Or can some boost numeric types, or
help somehow to deal with it?
In addition, not important.
In pages http://en.cppreference.com/w/cpp/types/numeric_limits/infinity
non floating point numeric types can’t handle infinity.
Is it also applied to GNU Radio?
