I'm trying to implement DWT-OFDM in Matlab. But Matlab shows the message, only real value can be available for IDWT.

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????

did you implement the DWT OFDM system by using IDWT and DWT ??
if implemented can i get the code for the same ?

idwt function accepts Approximate coefficients and Detail coefficients corresponding to the wavelet as a real valued vectors. Try splitting the modulation symbols as inphase and quadrature phase components and implement idwt respectively.
