Thanks Damian,
But if I need to deal with the data on the channels of the WDM,How can I do that?
For example if I made matlab component that represent fiber, how can I get the individual data on each channel?
Also what the data that appear represent.
For Example when I used an example from Optiwave Examples “DP-16QAM back to back Transmission w nyquist”
when the matlab component ,the sampled signal vector length = 8 X Number of samples (in layout parameters) although it is only five channels.
what the sampled signal represent in that case?
