it shoudl provide two separate models

Hi, Kumar;
What if a model wants to support non-linear time domain
simulation by GetWave and statistical simulation by returning a LTI
approximation
in Init?
Thanks,
Fangyi

i agree..
if the model modifies the init it is the only thing it should be doing. there
should not be any getwave

Dear
colleagues,
I
would like to clarify one basic principle of AMI modeling, hoping that all of
us agree with it.
I
believe that the model writer should never do a double-counting: if he
modified the channel impulse response in Init() to model some effect, he
should not model this effect in Getwave(). So he cannot put the “true” model
in GetWave() and it’s linear approximation in Init(). If both types of
behavior are expected, there should be two models (or some internal flag that
changes the behavior of the model).
If
this assumption is true, statistical (linear) simulator always works with
Init() function of the model, while pattern-dependent (non-linear) simulator
works with both Init() and GetWave() and I do not see any necessity for
Get_Wave_Exists flag.
Best,
Danil
