I'm curious what people do with the wideband capability of the gnuradio/usrp
and what is the widest bandwidth signal one can really process with available
computers?
For reference I have a ~2.4 GHz core 2 duo laptop. For a 200 kHz FM demodulator
I consume about 40% of one cpu. That's pretty much the simplest useful thing
anyone can do so that maps to my laptop might be able to process 1 MHz
bandwidth continuously.
Similarly, my hard drive can't really keep up with 32 Mbyte/s recording. So if
samples are 16-bit and you really can't afford lost data it seems like
recording is limited to maybe 10 MHz or so bandwidth.
However, with gigabit Ethernet you can send 100 Mbyte/s or more. What's the
most anyone has recorded or processed continuously? What level of compexity was
the processing?
Thanks,
Clark
