ofdm blocks

hi friends i'm student in last year of electronics & comm. engineering my project is vhdl implementation of ofdm , i have all blocks of ofdm with each code individual ,but i do not know how connects them togather to make it as integrated system

Re: ofdm blocks

if u have conceptual prob. this doc. may help
bt if u have prob. in implementation let me know

Re: ofdm blocks

Hi we too are in the same problem. pls go thru some of the ref designs by HARDWARE IMPLEMENTATION OF OFDM TRASNMITTER AND
RECEIVER USING FPGA by SHAHBAZ ABBASI (google it) This in verilog

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
