Hi everybody,
this is probably a silly question, but there's one thing i cannot fully
understand.
Considering that the 2 ADCs per channel on the USRP allow complex
samping at 64Msps, and therefore a 64MHz Spectral Bandwidth, and that my
inexpensive PC just needs 45% of CPU calculation power in order to make
an 8MHz wide FFT of the 8 complex Msps allowed (as a maximum) by the USB
2.0 bus,
doesn't it look like the USB 2.0 is a heavily constraining bottleneck?
And, if I'm not wrong about this, will it be possible in the future to
have a USRP <--> PC interface which doesn't limit us so much.
thanks
(...and apologies in case this question doesn't make much sense)
