ofdm blocks

think standard QPSK modem blocks

Tx and Rx

and then on the output of the QPSK_Tx feed a FFT module

and to recieve

come in through an inverse FFT module then into a
QPSK_Rx module

of course you should have some sort of
Forward Error Correction Like Reed Soloman
and you need to work out Sync for reception
