Default Does anyone have a good tutorial on COFDM?

I'd like to know about the DVB-T standard, but I get confused when it
comes to configuring a DVB-T system for a Single Frequency Network
topology. I've read that normally for an 8MHz bandwidth using 2k mode
about 1700 carriers are possible. Does this translate to 1700
individual programs?

I think I can probably answer this question if I find a good tutorial
on COFDM. I've found some on Google, but I haven't found one that
explains simply how it is possible to have multiple carriers in a
single channel.


Crossposted for a useful purpose.

The alt.video.digital-tv newsgroup has been home to numerous discussions of
COFDM and the various ways it's being employed. It was a contender for US
broadcast DTV but it lost out to 8VSB in a decision process that some people
said was political -- or worse. One of the leading proponents of COFDM
posted to alt.video.digital-tv as "Bob Miller," although he has nothing
there currently.

Bob Miller may have the material you want, given that he has
been a vocal advocate. The viacel.com web site comes up blank; I hope that
email address isn't a dud. Good luck.
