Thanks, Richard. I'd have been happy to learn that indeed Doppler
shift does lead to dispersion -- "any day I learn something new is a
good day." But coming to agreement was also good. Now, for the next
part of the story, Doppler shift _in_combination_with_ multipath indeed
does lead to dispersion, I believe. That's why I was careful in my
original question to say, "Doppler alone?" See for example
http://www.eleceng.adelaide.edu.au/s...grad/Yu05.html. I
get the impression that Ms. Yu is a pretty bright young woman.

Cheers,
Tom

Hi Tom,

I'd gotten it in my mind that the higher sideband would have increased
more in relation to the carrier than the lower sideband would have (or
versa vice) hence dispersion. Scribbling out the math in response to
your questions resolved that error.
