Hi,
That's right for GMSK but it would allow to use other modulations than aren't supported by the DSP like 8-PSK(?), 16-QAM and 32-QAM for EDGE. GNU Radio should have dempdulators for that.
True ... I tought about that myself. but until someone does it for the USRP first, it's not much use.
Of course it's more or less useless without having an implementation for GPRS first.
Have a look at the CCC camp talks :)
Beside the coolness of using these devices as a frontend for GNU Radio. :-)
Well capturing a continuous stream of IQ sample (vs a burst) would be pretty hard ... Besides 2 * 16 * 270833 is a lot of data ... about 10 times more than you can send through the serial port so getting them out the DSP into the ARM is only half (ok, make 3/4) of the problem.
Cheers,
Sylvain
