RE: stds-802-16: 802.16 and the Single Carrier



Hello Hank,

Thankyou for your comments. The market decides which will survive, but what 
drives the market? The mere sound of, "Orthogonal Frequency Division 
Multiplex", sounds far superior to the boring, "Single Carrier". For that 
reason alone, those who know no different will purchase the OFDM(A) 
solution, and pay the higher price for it too, thinking they have the 
superior solution! Hey, that's life!

I've had 22 replies to my email on this subject, all of whom agree there 
should be a single phy, 20 of whom agree the Single Carrier to be the main 
contender and 18 of whom mentioned the nightmare of trawling through so much 
(quality) information.

Did you ever see Dr. Falconer's tutorial in Ottawa, where he compared OFDM 
and the Single Carrier (and maybe a tad of CDMA)? He clearly demonstrated 
OFDM has no advantage and is a more expensive solution.

Take good care of yourself,
Joanne
