Bernard,

It seems to me that the advantage S-CDMA has over other methods, (QPSK, QAM16) is that it has the ability to run when the others fail. (<19db) As I understand it you are buying about 3 or 4db.....but that it runs in a degraded state. (not at optimum throughput) When you get down on the range of 15 - 19db the performance / throughput is reduced by 50% or more. (Is that true?) So though an operator gets a "graceful" degrading it would still necessitate the need to fix whatever ingress problem is affecting the network. So from my perspective S-CDMA buys you some margin / time to fix the problems, but no operator would let the plant remain in that condition.

Does that make sense to you? I apoloigize if my message is somewhat confusing.

Cheers....

Shawn
