As I know, the modulated data will be into IDWT instead of IFFT for OFDM.
I thought just changing IFFT to IDWT would be enough, but IDWT showed message only real value can be used for IDWT.
as the modulated data consists of real and complex values, I cannot use IDWT function for OFDM now.
How can I use IDWT for the modulated data for DWT-OFDM????
