Jose,
we're talking about this flow graph, right?
http://gnuradio.4.n7.nabble.com/file/n54534/ofdm_tx.png
In this flow graph, you're trying to find the individual symbols in time
domain; that's not possible, they only exist clearly distinguishable in
frequency. That is why there is an DFT (in this implementation, the FFT)
in OFDM!
Best regards,
Marcus
