Check out the 'digital_bert_tx.py' and 'digital_bert_rx.py' (bert = Bit Error Rate Test) in gr-digital/exmaples/narrowband for this kind of thing. Make sure you update from Git beforehand. I just remember when starting to reply that it uses an SNR estimator that was removed from gnuradio-core into gr-digital. It should work now.
