Yes, you told us three times. But I still don't believe it.
For something to be a solution to the ATSC "robustness problem" it must
be a commercially viable solution. If that was really so then we would
see plentiful examples of that solution for sale.
I don't think almost anybody much cares anymore how good ATSC looks on
paper or in carefully staged demos with one-off prototypes.
