I don't agree with Doug's comparions of HSDPA (WCDMA) vs LTE, either
in terms of spectral efficiency (which is in fact identical if you
use MIMO and the same channel widths in both cases) or in terms of
immunity from multipath. I think that comparing CDMA with 8-VSB, in
terms of multipath performance, just because CDMA is a single
carrier scheme, is very misleading.
Nothing misleading in this article to me. win to me.
A migration to LTE broadcasting would provide improved spectral
efficiency, a much wider range of potential services and the ability
to leverage the same infastructure as that being used for broadband.
Sounds like a win-win to me.
But Mr. Lung's final paragraph is the one worth paying attention to:
Whether or not ATSC-EV is the ultimate solution, it seems clear
that TV broadcasting has to be given the regulatory opportunity to
modify its transmission technology to keep up with other industries
if broadcasting is going to survive. Figuring out how to get there
from here without disenfranchising a large number of viewers is the
tough part. Sinclair received help from engineers at Rohde and
Schwarz and SES World Skies in its FCC presentation.
Actually Doug is overstating the problem with disenfranchising
viewers. Even the shift to ATSC did little to disenfranchise anyone.
What is far more important is how to get "a large number of viewers"
to actually watch OTA TV again.
