Al,
Since the patent was issued six years ago, can I assume that no product has
been made thus far using this technique? Is the theory much easier than the
practice?
I've always wondered how you can use the data segment sync bits to estimate
multipath when you first have to demod the 8-VSB before you can read the
data segment sync bits, which means you have to equalize out multipath,
which means you need to estimate the multipath. All very chicken and egg to
me.
