Hi everybody.
I’m done with my 4-QAM DDO-OFDM WDM system now. But I want to develop it to 16-QAM.
What parameters should I change?.
I known the bit per symbol of QAM generator and reference bit rate of OFDM demodulator OS12 must be changed.
How about the cut off frequence of filters and bandwidth of MUX (DEMUX)? What equation i can use?
If you have time please answer me.
Thanks and regards
