[Discuss-gnuradio] USRP: FFT on FPGA?

[Jens Elsner]

Hi,

is it feasible to implement an FFT directly on the
FPGA in the USRP? 

I would like to use the USRP for spectral analysis, 
a 512-point FFT (and windowing) would greatly reduce
CPU load. A "hardware" FFT would also be a great plus
for OFDM waveforms.

I don't have any experience in FPGA programming, 
just wondering if it's possible.

Best regards,
Jens
