How can I call filter coefficients in bit reversed order for HDL FFT?

Hi everybody

I'm working on a matched filter based on FFT/IFFT for HDL.

For efficiency purposes, I configured the FFT output for bit reversed order and I enabled the xk_index output.

I calculated my matching filter coefficcients of the refernce signal offline as it is always the same.

I know that I have to use this xk_index output to feed the correct coefficient to the complex multiplier. I just don't know how to do it in HDL.

Any help is welcomed.
