I have been trying to plot EVM v/s Received power in a DD-OOFDM system. The constellation seems to be good. Also the BER shown by BER Test set is zero. But I can see that EVM is not zero, not an issue. Now my problem is, when I tried to plot EVM v/s Received power in the Report window of optisystem, the plot showed the EVM at zero too, which by seeing the EVM values given by OFDM demod is clear that it is showing wrong plot. Also, the eyediagram for OFDM system seems to be unusual. I could have attached my design here, but since the attach option is not available, it couldnot be done. I am using optisystem Product Version: 13.0.3.474.
Thank you.
