Need some help with Matlab code for optical transmission.

Hi friends,

I really need a Matlab code urgently. The problem is actually transmiting a pulse through an optical channel having a transfer function which is related to chromatic dispersion. I just need a code for inputting a pulse through a fiber channel with some transfer function and to obtain its output.

Hope someone could send me a reply. Thanks in advance....
