We’re working with Uzair B. who has been in contact with you over some
issues before. We’re trying to implement a simple point-to-point digital
communication system in GRC. I’ve attached the snapshots of the
flowgraph
for you to look at. You can have a look at all the settings.
If we remove the packet encoder/decoder blocks, then we receive
something
at the scope, but it’s not correct. However, if we include the packet
encoder/decoder, then we don’t receive anything at all at the scope. We
figure it may be either because of our incorrect settings of the USRP
sink/source blocks *OR *the LO offset at the receiver results in so many
errors that the packet decoder isn’t able to decode anything.
We’ve also tried the .grc file you mentioned at:
Dbpsk on gnuradio-3.5 and Ubuntu 11.10 - GNU Radio - Ruby-Forum. This is working in simulation
but
once we connect the sink/source block, it’s the same problem all over
again.
Please guide.
Thanks,
Paymaan
