cross correlation of OFDM

hi i have been trying to implement multiplierless cross correlation of OFDM for IEEE 802.16d and i am stuck on the part as to how should i represent my correlator coeffiients . as they are in complex...

yes i was working on that previously but designing a working receiver of OFDM was too much work so now i am focussing on just creating a multiplierless correlator that is by using shift and add. i read about it ...is it not possible to do cross correlation on two binary numbers coz i read that only floating or fixed point input is used for that? as i want to use 8 bit numbers and then get to the correlator output using shift add and how to do i proceed with that. can you provide with some data or idea how to do it

and about the OFDM coefficients i read a paper about multiplierless correlation of OFDM if you want i can send you that
