    Thank you very much Alistu!

    A final question, do you know how to enable the Project Browser in Optisystem 7 on Windows 7?
    This option is enable only in Optisystem 13…

    Similar to the graph generated in matlab, in this case the OCDMA coherent represented by blue graph and the OCDMA incoherent represented by red graph for example…

    Ok Alistar, I’ll work in this project for obtain some other results relevant for my system, thank you very much for your replies!

    Hi Alistu,
    I compared my simulation with SAC-OCDMA simulation, but I have considered a ideal system therefore I have got better results, but I still not sure if I have done the logic correctly for shift phase using Matlab blocks according what to my system require.

    Hi Alistu, thanks for your reply.

    I’ve used Matlab to implement phase shifts the signal, according to the Hadamard code I applied 0 or pi to the frequencies set corresponding to these codes, thus I used the frequencies that the FBG were reflecting on the SAC-OCDMA, I applied shift phase of 0 degrees for these frequencies, and I applied shift phase of pi degree in the other frequencies, what featuring SPECTS system, I am using the modulation OOK, but in the future I will implement PSK or QPSK modulations. I used Matlab for it because I haven’t found components in OptiSystem that satisfy this condition.

    Thanks Ravil,

    I’m just a beginner, so, I’m sorry about some issues, however, I hope to contribute in every way in this forum!

    Hi Damian,

    Thanks for your reply!

    Well, I already had seen this topic, but I wasn’t understanding how I could relate each wavelength with the pre-defined Hadamard code!

    However I’ve read it again and I think I got it!

    I am a beginner in a Scientific Initiation in OCDMA in my University and I’m really get excited about the software OptiSystem!

    Sorry about my English, I’m from Brazil!
