[Discuss-gnuradio] Decision making and Python/C++ Blocks

[abbasi9999]

Dear all,

I searched the forum but there was no answer for these questions:

1. for a simple energy detector we have some equations which usually use the
inverse erfc function. when making the the dicision using either
spectrum_sense.py/usrp_fft.py (which one do you recommend for accuracy -for
large range its the first-?) how can we apply this function (there is no
module for it)?. 

2. calculating the threshold need some math operations and functions, do we
have to make the C++ file then use swig to make a module for it or we just
can do it using python?? please recommend and why?

best regards,
