Have you tried regular 8-VSB, with diversity antennas, and on a chip
like the Samsung Gemini, which has considerably better dynamic echo
tolerance than the LG 5th Gen?

Compare apples with apples.

Say what you will, but if you compare how close A-VSB gets to the
Shannon limit, with the best either DVB-T or the new Chinese scheme can
do, it holds its own with no apologies.

At some point, the persistent pessimists will have to finally accept
that modulation complaints are a quaint anachronism, and there are many
more fun things that they should spend their time worrying over.
