David,


Ø  I meant passing in the list of numbers, [0, 1, 0, 0, ...]

In my view, this one should be scaled by multiplying on Sinf/step, where Sinf 
is the desired step response at infinity, and step=Tbit/samples_per_bit. Some 
models ignore the numbers if they are too small.
I would modify this idea by calling init function twice, with a certain 
realistic impulse response and similar response modified by adding you sequence 
([0,1,0,0], this time without scaling. By finding the difference between the 
two output responses, we immediately get the characteristic of the model's 
filter.

David,

I finally got it...  Sorry that it took me so long to
understand your question, my mind was stuck in the
time domain setting of channel characterization.

I agree with Walter's answers to your question.

I meant passing in the list of numbers, [0, 1, 0, 0, ...], in the 
`impulse_matrix' parameter of the `AMI_Init()' function.
