Dear sir, this is practice file, if we use coherent detection, we get I and Q component but we do not use access technique like OFDM-QAM in the transmitter so do not use at receiver as well. my problem is how to combine two signals(I/Q without using OFDM-QAM) to feed them to 3R REGENERATOR AND BER ANALYZER(because these are one input polarity modules and we have two signals from coherent detection)
HELLO,
Under same CO -OFDM, I HAVE ONE QUESTION. I AM UNABLE TO DO SOME PARAMETER SETTINGS WHICH SAYS
“FOUR receivers are designed to have the same parameters except for the center frequency of the receiver and the local oscillator which will be identical to the wavelength of the laser transmitter”
perhaps due to unability to understand above qouted work, my co ofdm QAM module at reception after Coherent detection does not work. help needed for this

Dear sir, this is practice file to build some concepts about optisystem functioning co OFDM, I find no results or no QAM WORKING, I find after there is a problem after coherent detection.
2nd question.

co ofdm , i find no results or no QAM WORKING

hi , can you see out co ofdm structure , i find no singnal at QAM , no final values
