Hello:
In trying to execute the flowgraphs found in the blog post on the subject
at:
http://www.trondeau.com/examples/2014/1/23/pfb-channelizers-and-synthesizers.html
I find that the Busport connections in flowgraphs such as
fm_reconstruction.grc and others are broken when they connect to the QT
Hello:
Just chiming in with the fact that I am struggling with this identical
issue using a "Dizzy" build for an Ettus E310 running on the device.
I have tried a number of different example flowgraphs that utilize QT GUI
and have come up with the exact same error

Hello Daniel, hi Rich,
if you actually want to pass a string as PMT, the pmt::intern("..") is
ok (although it has a performance penalty[0]).
If you want to simply sent byte buffers, the uniform vectors approach
would be the best (have a look at make_uvector8).
As for a simple example of message p

This sounds much less like a problem with regards on how to figure out
the synchronization but more about how to do it inside the confines
Hello Daniel,
Are you using OFDM? If so, read on, otherwise disregard the rest of the
email.
Please look at the Schmidl-Cox synchronization method (Robust Frequency and
Timing
Synchronization for OFDM). In a nutshell, the frame detection works like
this:
At the transmitter, the packet is created
I'm very interested to learn the answer to this. I'm trying to do the same
thing right now.

Hi Maroti and Braun,
I ran into a similar problem. I tried to set the ninput_items_required[i] =
1, then the same output
sched: is requesting more input data
than we can provide.
ninput_items_required = 1
max_possible_items_available = 8191
If this is a filter, consider reducing
