Ifft for dvb-t - looking for an algorithm

[farshid1354]

ifft dvb


I am trying to find an efficient IFFT algorithm in order to use in dvb-t modulator and then implement it on fpga.Can anyone introduce me such algorithm?
If can please send its to me paper.

my email:farshidfarr2003@yahoo.com
thanks a lot.

You can use radix-4 structure.
opencores has a free ip about it.

Re: Ifft for dvb-t

Hi
it is similar to fft.
first write a program for fft and then by some manupolation you can chang your program to ifft program
