Packet encoder problem

We are using the following setup for a point to point TX RX Path:

TX: File Source → Packet Encoder → DQPSK Modulator → USRP Sink

RX: USRP Source → DQPSK Demodulator → Packet Decoder → File Sink

We want to compute the BIT ERROR RATE for the process. We have figured
out
(or rather assumed) that the packets which are not received properly on
the
receiver end are DROPPED. Therefore, the received data file created has
a
lesser size as compared to the source data file.

Since the packets with corrupted data bits are dropped, we can only get
to
know about the packet error rate (and not the bit error rate). Please
guide.

Best,
Huzaifa

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.
