Regarding OFDM demodulation

Hello sir,
I connect OFDM simple block diagram as shown below.I got OFDM
Modulated
output but unable to get OFDM Demodulated output.Will you please suggest
me
any solution for this.
Thank you Sir.

Dear Gaddam,

I think your symbol generation is a bit weird.
I think you want to send binary data, but you convert that to float
before passing it to OFDM mod. I’m pretty sure that’s not what you
really want to do – just set the input type in the OFDM mod block to
byte, short or int, and generate random numbers between 0 and 2^8, 2^16
or 2^32, respectively, using the corresponding output type of your
random source.

Anyway, you’re not giving nearly enough information to help you – “not
getting demodulated output” doesn’t really indicate what goes wrong. Try
the recommendations in [1], to give us a more meaningful description of
the problem.

Best regards,
Marcus M?ller

Hello sir,

There’s not only “sirs” on this list, but also “ladies”, and maybe a few
artificial intelligences, so maybe just say hello :wink:
