Hi Antonio,
I think this is a revival of an older thread.
I still can't execute your flow graph, because it seems to be built with
an old version of GNU Radio (probably 3.6.X?).
Using that really doesn't make sense for OFDM experimentation, because

Hi Rama/Dave - I can't say -why- the error is happening, but the error
is because for some reason the llibusb1 library is not being included in

I'm trying to demodulate a CPFSK signal using the Viterbi algorithm. The
gr-trellis module seems to have most of the components I'll need, but I'm
having trouble figuring out how to wrangle my problem into the FSM format.
Basically, I have a binary CPFSK signal with a modulation index, h=25/3.

How about do none of the above ...

Since most SDRs out there have fully reconfigurable-by-the-end-user FPGA
and firmware images, I don't think the notion of "compromise"
has much meaning in this context, further because access to the devices
is freely available to ordinary user-level processes, they can ask the

Even better, how about a graph of attendance at each GRCon?

these are two different aspects:
