Here's an interesting paper, from Prof. Jean-Yves Chouinard
of Laval University, Quebec, and from our friends at the
CRC in Ottawa.


It was presented at the IEEE Annual Broadcast Symposium in
October of 2004.

It documents measurements taken in mobile ATSC reception in
urban, suburban, and rural environments. The receiver relies
only on the data field sync segments provided by ATSC, and
the PN-511 training sequence in particular. They also
demonstrate the effect of diversity antennas, and conclude
that diversity antennas are necessary for mobile reception.

The training sequence itself does not occur often enough to
give, by itself, channel response at speeds greater than 28
Km/h. The measurements were taken for speeds from 30 Km/h to
100 Km/h (i.e. 18.8 to 62.5 mph).

I haven't read through this carefully enough yet, but I
figured others might be interested to give it a look.
