I notice on the Wiki that the conjecture about the bandwidth of

neat to see, but it left me with a question (which I hate to spam
the Wiki with.)  Is it the case that the USB2 bandwidth is
sufficient for 1/1, but the overhead of related CPU-side
processing brings the ratio down?

That is correct.  The USRP is fast enough to handle HDTV in real time, but the
PC is not (yet).  I suspect that with a little bit of tuning, and some offload
to the USRP FPGA, that it could be done.

BTW, Eric and I are in Utah right now demonstrating the USRP for an NSF crowd.


I really had in mind something like this:


There is a linux port to this,
with a custom spin of the USRP. I'm kicking around a Gnu GPS project, and portability in a GPS is really key. Of course, once you have that, lots of interesting things become more possible.
