Please do anyone know the input and output scaling for saleh model in simulink under these conditions.
1. negligible nonlinearity
2. moderate nonlinearity
3. severe nonlinearity
thanks

For modeling non-linear amplifier, it is better to use a table lookup. particularly if you have data available. Instead of curve fitting as Saleh does, why not let the simulation do it.
The definition of the various types of non-linearities tend to be subjective. Only thing we can say is that any thing that is close to a hard limiter is a strong non-linearity and anything that is close to a straight line or of exponent less that 2 is mild.
