Is possible to have a FFT using the cordic algorithm. At opencores you can get a configurable one. I used it some time ago but I don't remember the percentual of FPGA utilization, or the use of any multipliers. Euripedes 2011/3/12 Matt Ettus > On 03/11/2011 06:06 PM, Alaa Salaheldin wrote: > >

Here at UFES(Federal University of EspĂ­rito Santo - Brazil) we are starting to work with GNURADIO trying to have a decent lab. We plan to use it for simulation and "real" tests, but the the brazilian bureaucracy is a real, and very hard, obstacle to us. We'll have a basic course in communications s

Just to place some previous experience I have, if you have diferent configuration parameters, the hardware, possibly, will not work!!! Same code without change nothing, and will not work. This is not a USRP issue, FPGA projects can go wrong with diferent parameters for synthesis. 2011/1/12 Matt Et
