Thanks for your concern.
As the input is having hermitian symmetry, there is no imaginary part. Now, if the output terminals of OFDM block outputs real and imaginary parts in the 1st and 2nd terminal, then how can I get the imaginary signal if the input is having hermitian symmetry? I don’t know whether my knowledge is in right track or not, since I am new in the field of communication.
Thank you once more
