      Good day,

      We have examples of several OFDM systems under Advanced modulation systems/OFDM systems. The coherent examples are the best ones. I recommend taking one of these and converting to a direct detection. The Help section of the OFDM Demodulation component is very good too. It provides information on how to setup the parameters. Cheers.
