No output from the Packet Decoder?


#1

I’m hooking up in GRC a packet encoder to a DPSK modulator and then a
decoder to a DPSK demodulator and everything seems to be fine up until
the
output of the packet decoder. I got a signal going into it, but
nothing
coming out…either on a scope or file sink. I’ve played around with
the
threshold on the decoder (-2,-1, 0, 1, 2) but nothing. I called myself
looking but don’t see any examples on the Packet encoding/decoding.
I’ve
got the encoder packet lenght set to 0 for automatic. I’m doing DBPSK
and
got the Sample/symbol set to 2 and bits/symbol set to 1. I looked at
the
the python code and it looks like to me you should be able to connect
both
the decoder and encoder directly up to the DPSK Mod/Demod…correct?
Any
thoughts?

There is now a simple loopback example with dbpsk in the trunk
http://gnuradio.org/trac/changeset/10632

The example works, seems to be a little laggy, though that might be my
computer. I cant wait to use/implement some real message passing
interface blocks for the packet encoding and decoding. :slight_smile:
