<He pointed out that no-one worked on cars anymore.> Pretty much true, in part due to smog regulations, in part due to complex electronics, etc on new cars. Not sure what young people are interested in now, video games and skateboards?. All of a sudden, all of the cellular service providers are giving very good deals on long distance. Must be telling us something, some soon going out of business? More mergers? We have Sprint, VZ, ATT, Cingular and Nextel all competing here. Display in almost every store now, not many sales, only the VZ store is busy. Lots of unused fiber yet, if the stories are true.

One thought about OFDM, it seems well suited to situations which would require very long time domain traversal equalization, such as terrestrial broadcast digital television, where there are few transmitters and potentially very long echo paths. In the case of cellular communication, the cells are much smaller, so multipath should also be much shorter. This could lessen that benefit of OFDM, but I don't know how the tradeoffs work out in practice. Has anyone come across anything? I haven't been closely following the engineering literature the past few years and am really falling behind on some of these things.
