-the point with the CDMA cocktail parties is to have small, sensitivity inefficient cells.

Normal RF stuff can be extremely sensitive, like AM,
FM receivers, if the RF filters clean up all the
adjacent bands, no other signals are present in the band,
high linearty is not a must.

-low dynamics,especially because of need for tight,
limiting power control.

Should have added the need to transmit and receive at
the same time, not like GSM which doesn't do it
and can pick up those low level signals without
blasting its transmitter att full power at the
same time.

but the complexity of the received signal also demands
much more in terms of dynamics, linearity, stability
(power level) to successfully dig out that one channel
from the CDMA cocktail party.

But with small enough cells and capacity to waste all of
this doesn't really matter.
