Dear Ahmad:
Wow, it works! Thank u so much Mr. Atieh!
But after I used WDM analyzer, there still one question:
I used QPSK to build OFDM system, and the WDM analyzer always tells me signal power equals 0. Is this because of QPSK or because I used only one wavelength?
If there is an offense, please forgive me.
