You are right about how I find the coefficients. However I do not
understand why it should not work for a nonlinear channel. The algorithm
might not find the optimal coefficients but no matter how the
coefficients are found, the simulations show that the filter is able
compensate the distorted channel.

Regarding the computation of the EDC coefficients ("using MMSE"), could
you be a little more specific? Did you use an adaptive algorithm to
compute the tap values from the simulated waveform? Typically I think
of MMSE as referring to an analytical solution for the tap values, but
I'm not sure how that would work with a nonlinear channel like this one.

Regarding todays meeting:
EDC coefficients are obtained using MMSE and yes see the hanberg_1_0304
presentation for BER calculation.
We are able to simulated lasers with peaking and ringing by changing the
gain compression factor. Attached is a figure showing one of the
lasers with a lower gain compression coefficient (eps_nl =2.22e-007).
Any views on how realistic this looks?
