implementing OFDM by using Xilinx blocks in Matlab Simulink

Hi,

I am implementing an OFDM tranceiver by using xilinx blocks in order to generate VHDL code to be downloaded in Xilinx vertix 4 or 5. My problem is that how can FFT 7.1 in the receiver know the first bit of OFDM symbol? We are assuming the delay of the channel is unkown, and the receiver is synchronized. In other words, do I have to use algorithem or another technique like framing bit to deal with this ploblem?

However, I am feeding a delayed signal from IFFT 7.1 to FFT 7.1 since I know the delay, but If I don't??

 

Regards
