I want to start expereiment with software defined radio but can't make up my mind which one of the usrp and usrp2 is the most suitable.
I am new to FPGAs but want to start playing with these as well. I use GNU/Linux and GCC as much as I can.
Some questions:
The usrp and usrp2 uses FPGAs from different manufacturers so I assume the development environment will differ as well. Is anyone of the two more suited for a linux system than the other? I don't want to pay any license costs (and I'm glad if I can use the dev environment longer time than a trial period... btw, I am a student).
To play around with a FPGA on a system like this, will I need the extra size and speed xilinx spartan 3 gives me? (Maybe I want to bruteforce some cryptos, doing some FIR filters or event wavelet transformations)
Since the usrp2 only have one tx/rx channel I would need two usrp2's to get the same number of tx/rx channels as the usrp and this is not currently an affordable option. In which cases will I need two tx/rx channels? Examples?
The usrp2 is faster in many ways. In what applications will I need the extra speed and extra bandwidth? Examples?
Any other cool stuff I can do with one of the boards but not the other?
Are gnuradio programs written for usrp compatible with usrp2?
Thanks!
Best regards,
Manne
