SAC OCDMA

[Teena Sharma]

Hello,
i m implemeting SAC OCDMA system and trying to simulate various codes on it. I am unable to understand compementary detection technique by using FBGs. Like in Decoder part using FBGs the upper part is same as encoder while lower one is just complement of it. I am not getting how and what the wavelengths has to be assigned to the lower FBGs. and why we are using complement of encoder.

which example you are working in?

thanks

Hi Goswami
Plz let me know the example file so that i can comment

hello ,

i m attaching example file ..it is sac system given in examples of optisystem 15. i m not able to understand hw detection process takes place…i mean if we are using codes having cross correlation 1 then how MAI gets eliminated using detection tech. and which is used and how FBGs wavelengths are selected in decoder part..

regards
Teena
