TDM = Time Domain Multiplexing
WDM = Wide Dimensional Multiplexing
SDM = Statistical Domain Multiplexing.
TDM and, to a limited degree, WDM have been around and used for several
decades in high performance networking. SDM is relatively new, about 5
years.
There are far more ways to multiplex intelligence on a medium than PSK and
FSK, although both are used in high performance systems.
You are 100% correct... I may very well a few decimal places off... The
mathematical models show that 100 Mbps should be possible in as little as
10
KHz.
The model is wrong.
Post it and I'll be glad to explain why.
