You can always use the ATSC transmitter in GNU Radio to generate a reference IQ stream. It will have very high SNR, but will work fine for efficiency improvements.


Here's a properly formatted Transport Stream that you can use for the TX flow graph.


The sample rate of the IQ file will be 4500000 / 286 * 684 = 10.7622 Msps. You'll have to change the sample rate in the ATSC receiver to match that.

And yes, you'll never see DVB-T2 in the US. "Not invented here". For testing the DVB-T2 code, I had to import a USB receiver (PCTV 292e) from the UK.

Thanks for response Tom and Ron.

I'll take a crack at improving the ATSC decoder efficiency first, just
to get my feet wet with GNURadio again. Tom, are there test vectors
available for the ATSC 1.0 decoder?

Whether or not ATSC 3.0 will ever be a thing... I agree with what Ron
has said, and I don't know if it will ever succeed. But with that
said, ATSC 3.0 has a better chance in existing in NA as opposed to

I'm definitely in wait and see mode on this standard. This is pure
speculation, but I have a feeling that ATSC 3.0 may never see the light of
day. Some reasons are:

1) There will be no second channel and no government funded converter box
program like the analog to digital (ATSC 1.0) transition. Unless the FCC
mandates that all TV's must have an ATSC 3.0 tuner and until these TV's
penetrate the market, no station is going to switch over.

2) If the upcoming 600 MHz incentive auction is successful, then there may
be large number of TV stations that will need to change frequency after the
repack. There will be some government financial relief, but it's likely not
to be nearly enough. After spending large sums of money getting on a new
channel, TV stations may not be too keen to spend more money on ATSC 3.0

3) One of the main features of ATSC 3.0 is mobile TV. But mobile TV has
failed over and over again. The primary reason is that no cell phone
provider will put a mobile TV receiver in a handset. Without some "killer
app", ATSC 3.0 doesn't provide enough incentive to upgrade.

But I could be wrong. :-)

Hi GNURadio folks,

Some portions of the candidate standard for ATSC 3.0 have been posted
to the ATSC website (http://atsc.org/standards/candidate-standards/),
and specifically the PHY/bootstrap sections are now available.

As far as I know there is no one working on a GNURadio version, but I
thought it would be worth while to check for collaborators before
venturing out.

Note, this would be a personal project for me not for a dissertation or
