I received my USRP and successfully tried the gnuradio examples on it.
Then I tried digtal & gr-trellis examples.
The gr-trellis/src examples worked fine as mentioned in the read me file.
>>> I was trying to transmit few convolutionally encoded packets and receive ( decode ) the same using Viterbi decoder at the receiver. Now, I could transmit / receive the sample packets using benchmark_tx.py and benchmark_rx.py Thats about it. But i couldnt encode my packets. My understanding is that by default these packets are not encoded. I tried going through the library files (
trellis.cc, trellis_viterbi_b.cc), but got lost in between. The gr-trellis.xml wasent helpful either. Can anyone please point as to how (for testing) i can transmit convolutionally encoded packets and receive the same ? <<<
Since a generic encoder is implemented, i guess that understanding with the convolution example should be the easiest.
Thanks a lot.

P.S. Please excuse me if this question sounds like a newbie question.
