Hi Michael,
I'm just jumping in to advertise a GRC feature: if you use the
"screenshot" menu item (identical to the printer button in the tool
bar), you get a png of your canvas, rather than a picture of your UI and
everything.
Best regards,
Marcus

I abandoned the FSM constructor and decided to just use the decode
CCSDS27 block.

Michael,
I haven't seen your flowgraph, but as I wrote in my previous email you are
using the fsm constructor probably in the wrong way:
You are confusing the (n,k,K) parameters of a CC.
k = number of input bits per period
n = number of output bits per period
K = constraint length of the code (re
I'm going to post my flowgraph. I have added a CCSDS decoder block.
Please, if you can, provide input on how to improve the amount of
successfully decoded data with a short wave file and a doppler
shifting BPSK carrier.
My .wav file: http://1drv.ms/1bS3KxX
and here is my gnuradio flowgraph: http:
The problem is not the length 2048 but the way you use the fsm constructor
trellis.fsm(2,7,[79,109])
You are trying to create an FSM for a (7,2) CC.
This means you need to provide a vector of 2x7 integers, each
representing the generator polynomial between the i-th input (i=0,1)
to the j-th ou
How do I determine the block size? I tried several different
large/small values and they return similar errors.
Thanks,

2048 looks wrong.
