[Discuss-gnuradio] Large FFTs

[Thomas Hobiger]

We are considering to purchase a USRP2 + a DBSRX board in order to 
utilize it for some GPS stuff. Thus it would be interesting to know 
what's the maximum supported (implemented) FFTs size. I have checked the 
old discussions, but there's nothing really conclusive. What we are 
looking for is something larger than 16K FFT points.
Maybe someone has experiences with such large FFTs and how they perform 
(Flops or FFTs per second)?

Best regards,
  Thomas Hobiger
