This whole discussion may be moot for the time being...
There's some space in there if you disable some portions of the RX chain.
Plus there is a good amount of RAM stil

It uses the GNU Radio fft block,

Can you reconfigure the FPGA by changing some software based description
in a development tool (Quartus) or do you need to break out a soldering
iron or SMT rework station?
The facts are: what is run in an FPGA is SOFTWARE DEFINED.
I despise this dichotomy to the n-th degree and aver it is who
Well, thats good enough. But then, I havent still got the relevant
documentation on this anywhere on the trac. I mean, I want to know how does the
host side handle all the related (I)FFT stuff.
Please help me in this regard.
Maybe some USRP documentation on OFDM might suffice.
Thanks a lot.

Recently, Brian told me that the FFT-IFFT processing is handled by the host
side. Can I know how this is done exactly? Is there any relevant
documentation for this on the Wiki?

Hello,

side. Can I know how this is done exactly? Is there any relevant documentation
