Hii
Thanks for your responses.
The problem is this channel model is eating some initial 6 bits(3 qpsk
symbols) and last 10 bits(5 qpsk symbols).
Because of this index of output symbol is different fron input which is
resulting in error for all snr ranges.
You can see the output for noise_volage
Thanks Iluta and Nathan,
My problem was not being able to use the gr-tutorials examples if I didn't
have Gnuradio installed in /usr/local, but then I realized that the
gr-tutorials was also a pybombs recipe so I used pybombs to install it and
everything worked out great! Thank you both for helping

Just a quick follow-up,
we've gotten some feedback, and made some small changes, but it seems
overall this C-wrapper API will get merged soon. I'm taking down the
public branch for now, but you will get the codes back in master within
the next week.
Thanks, everyone!
